Unciv Crash Fix: Attack & Liberate Without Freezes

Hey Unciv players! Ever been in the middle of a strategic masterpiece, maybe liberating a captured settler with your trusty tank, only for your game to suddenly crash? It’s super frustrating, right? Especially when you're just trying to liberate a barbarian camp or execute a crucial attack. This article is all about diving deep into a specific Unciv crash issue – one that pops up when you're trying to attack or liberate, often involving a "Malformed Vector2" error. We'll break down why this might be happening, especially with all those cool mods many of us love, and most importantly, how to get your game running smoothly again so you can get back to conquering the world without any annoying freezes or crashes.

Understanding the Unciv Crash Issue: When Your Game Freezes During Critical Moments

Alright, guys, let's get into the nitty-gritty of this particular Unciv crash. Imagine this scenario: you're commanding your mighty tank, poised to attack a barbarian camp from the sea, and your objective is not just to clear the threat, but also to free a captured settler. Sounds epic, right? Well, for some players, this exact sequence of events, a tank attacking from the sea and liberating a settler, can trigger a game-breaking crash. The specific error message we're looking at, com.badlogic.gdx.utils.GdxRuntimeException: Malformed Vector2: HexCoord(x=-24, y=-22), is a real mouthful, but it gives us some crucial clues. This isn't just a random freeze; it's a specific technical hiccup related to how the game handles coordinates and alerts. When the game tries to show an alert popup about the recaptured civilian, it chokes on what it perceives as malformed coordinate data, leading to the dreaded crash.

This Unciv crash has been reported on Android, specifically with Game Version 4.18.18, often compounded by a hefty list of mods. The device information, like EB2103 and API Level 33, along with memory stats (7394 MB System Memory, 2056 MB Available, 18 MB Java heap free), tells us a bit about the environment where this bug occurs. While hardware specs can sometimes play a role, the core issue here, given the Malformed Vector2 error, points more towards software and game logic than raw power. The fact that the crash occurs on the com.unciv.ui.screens.worldscreen.WorldScreen indicates that the problem materializes right when you're actively playing on the main map, specifically during the update or render cycle, when the game is trying to process events like unit actions and display popups. What’s really interesting is the long list of installed mods: The Undead, Anime Multiverse, Civ V - Vanilla, Deciv 2, Brave New World, Resource Recyclers, Medieval Civilizations, UnTile Civ6 Tileset, Civ6 mod, Ningen no Sato Touhou, World Of Gensokyo Touhou Mod, Civ IV, Latin American_Civs, Smoky Skies Redux, Ancient Civilizations, Civ V - Gods & Kings, Maid Empire, My Uncivilized Ponies. While only a few were active during the specific save (Civ V - Gods & Kings, Ancient Civilizations and My Uncivilized Ponies, Maid Empire as permanent audiovisual mods), the sheer number of installed mods significantly increases the potential for conflicts. When the game attempts to addRecapturedCivilian to an AlertPopup, a process that requires precise coordinate data, and one of these many elements (the unit, the terrain, the liberation event, or a mod altering any of these) provides invalid or unexpected HexCoord values, boom! Crash. This kind of error is tricky because it's not always obvious which mod or interaction is the culprit, but understanding the context of the crash, particularly the Malformed Vector2 message, is our first big step toward finding a solution to prevent future Unciv game crashes during those crucial attack and liberation moments.

Why Your Unciv Game Might Be Crashing: Decoding the Error Message

So, why exactly does your Unciv game decide to throw a tantrum and crash with a Malformed Vector2 error when you're simply trying to attack and liberate? Let's break down this tech jargon into plain English. A Vector2 is basically how the game understands a point in a two-dimensional space – think of it as an (X, Y) coordinate. In Unciv, since it's a hex-based game, it uses HexCoord, which is its own special way of tracking locations on the hexagonal map. When the error says Malformed Vector2: HexCoord(x=-24, y=-22), it means the game expected a valid set of coordinates for something, but instead, it got something it couldn't understand or process correctly. Those x=-24, y=-22 values might be completely out of bounds for the map, or perhaps they're in a format the game's parser, specifically Vector2.fromString, couldn't handle, leading to the GdxRuntimeException. This is a classic case of the game trying to draw or reference something at a place it doesn't recognize or that simply isn't valid within its world structure.

Now, let's connect this back to your specific action: a tank attacking a barbarian camp from the sea to free a captured settler. This is a multi-layered event. You have a unit (tank) that typically operates on land, but here it's attacking from the sea. Then there's the target (barbarian camp on land), and the outcome (liberating a settler, which is a specific game event). Each of these components involves various game mechanics and, crucially, coordinate calculations. Here’s where the mods really come into play. With a list as extensive as yours – encompassing everything from Civ V - Gods & Kings to Anime Multiverse and My Uncivilized Ponies – the chances of a mod conflict skyrocketing. Some mods might alter how units move or attack, others might change terrain properties, and still others could redefine how events like
