Game Crashing / Stuck Game
anything can be a reason for the game to crash or Never Load.
Who is the likely culprit?
Clothing & Furniture Mods
Visual content like Custom Content clothing (CAS) and furniture (objects) is a very common cause of crashing.
Anything visual has to be rendered by the game and rendering is prone to crashing when it encounters issues. Any rendering problems will result in a game crash. Clothing or Objects that are causing the game to crash have to be removed from the game to fix this issue.
Technically any clothing or furniture mod can be the culprit. There’s no reliable way to test for it.
User Interface Mods
Visual content like modified or extended user interface (UI) is a very common cause of crashing and visual glitches.
Anything visual has to be rendered by the game and rendering is prone to crashing when it encounters issues. Any rendering problems will result in a game crash. User Interface mods that are causing the game to crash have to be removed from the game to fix this issue.
Mods like ‘UI Cheats Extension’ and ‘More Columns in CAS’ (or similar mods) can cause crashing and gameplay glitches when not updated for the most recent game patch.
Tuning Mods
Tuning mods, which are contained in PACKAGE files, like custom traits, custom moodlets, custom aspirations, custom statistics, custom interactions, etc. are occasionally the cause of game crashing and a very common cause of infinite loading.
Anything that provides additional gameplay content might involve resources (typically visual resources) that are dependent on the core of the game engine. Any problems with the core engine functionality will result in a game crash. Tuning Mods that are causing the game to crash or load forever have to be removed from the game to fix this issue.
Mods that provide resources required for visual representation of content (like in-game icons) can become outdated or were incorrectly made which can cause crashing and gameplay glitches.
Script Mods
Script mods, which are typically contained in TS4SCRIPT files, are rarely the cause of crashing and gameplay glitches. Script files are usually paired with PACKAGE files which might be the actual cause of crashing.
Script mods are rarely the cause of crashing, but are a common cause of gameplay glitches. There are very few cases where a script can cause the game to crash as they run separately from the core game engine. Any outdated or incorrect communication between a script and the core engine can result in a game crash. Script Mods that are causing the game to crash have to be removed from the game to fix this issue.
Scripts might cause crashing after a game patch that changes how communication between scripts and the game engine occurs.
