Found some outdated mods that ive disabled but yet i'm still getting crashes. Here's my lastest one.

I am not sure which mod added this twice:
PrefabMappingException: Duplicate prefab name TubewayStation.IronTeeth in objects: TubewayStation.IronTeeth, TubewayStation.IronTeeth.

Do you happen to add the Tubeway, and use Configurable Zipline and Tubeway option to add Tubeway to FT as well?

is this a crash log that u asked me yesterday?

Ah that makes sense... Since the Folktails bots don't have animation for Charging. Could you disable the Charging need (and Charging Station) for now please 😅?

yes i did,but charging needs still active, and the cant work)

Did you mean you cannot unselect the Energy need or you unselect it and it's still there? If the former, you have to uncheck the Charging Station building because that need is needed. If the latter it sounds like a bug.

I tested with a save with FT bots with the Energy need, then disable both Charging Station and Energy need in the main menu and go back, and it's not there anymore.

I cant unselect energy need for bots and it doesnt change the setting)

Did you unselect the Charging Station (in the Building section)? You have to unselect it before you can unselect that need.

my bad, i didnt check that moment. Now i uselect those needs and it works properly. God bless, thank u for helping me)
