Game sometimes crashing from opening train UI's
The game keeps crashing when I repeatedly open train platforms and I don't know why.
My mods aren't outdated.

FCrash reason in the logs
Assertion failed: Index >= 0 && Index < MaxElements [File:C:\BuildAgent\work\607eee041ab2bfcf\UE4\Engine\Source\Runtime\CoreUObject\Public\UObject\UObjectArray.h] [Line: 388]### Why the game crashed
You've hit the UObject limit. Unreal Engine has a large, fixed-size array to manage all UObjects at runtime (it's used for fancy things like "reference counting" and "garbage collection"). In pre-U8 this was very unusual and only happened when people made ridiculously titanic factories. However, it seems U8 has bugs that make hitting this limit substantially more likely, even when not building megafactories.
Details
In U8, something seems to be "leaking" UObjects, i.e. the UObject array gets fuller and fuller over time in spite of the garbage collector's best efforts. This crash happens randomly, but the probability of crashing increases the longer the game has been running for. Crashes are more likely to happen when opening UIs (the UI system uses UObjects to function), especially UIs that show many-slot inventories e.g. player, storage containers (the number of allocated UObjects is proportional to the number of inventory slots). Consequently, having many additional inventory slots increases the probability of crashing.How to fix
Coffee Stain Studios (the ones who made Satisfactory) will fix this in 1.0. Until then, consider these options:- Install https://ficsit.app/mod/Th3UObjectCounter, which warns you when the UObject array is near full, so you can restart the game before it crashes.
- Remove mods that add inventory slots and use https://ficsit.app/mod/DecreaseInventorySlot to reset your slot count to normal
- Instead of inventory slot mods, use mods that allow larger stack sizes (like https://ficsit.app/mod/StackOverload) or deliver items to you as needed like https://ficsit.app/mod/LogisticModules
Rnot the exact message you got but something similar
Rare you using modded train platforms with more slots? that would make this issue happen more quickly
RGiven that
UFGInteractWidget::OnCustomTick is in the stacktrace, it is likely
_I don't
_I have extra inventory slots
RHow many extra inventory slots?
RLots of extra inventory slots would make the issue even more likely tbh
RBecause any UI that shows the player inventory will create a lot of UObjects
