(Known crash AssertionFailedItemClass) Something has caused an inventory to run an invalid operation. It's probably not clear from your crash log which mod and/or building are at fault, but you can temporarily install the Inventory Tick Crash Debugger mod to troubleshoot this further. Remember to read the directions on the mod page about how to use it!

Please attempt to remove/disable these mods so that they no longer force the old SML to be used (this is why your mods don't load).

assertionfaileditemclass triggered by @Jevla@SirDigby Hi, silent ping. Does MLB cause crash when they trying to grab from a storage container at same time as another block do?
Because I was just standing idle when this happen
MLB snap directly on storage container and then other end to a machine. ( no belts )
No, it shouldn't cause crashes anymore. It hides a belt now instead of doing a direct connection
yeah I noticed that little bit after 😄
@SirDigby {Mod Name} Sometimes "Storage on belt" mod not working. Its attached and items flowing through it, then later it doesnt work and I need to pick it up and place it again. Maybe this is the cause of crash?
Just an idea I just got
I doubt it, it is just a small storage container at this point
Just use this If you want that https://satisfactory-calculator.com/de/blueprints/index/details/id/9622/name/Storage+%281+slot%29
