Stone heart crashing at start up (fixed)

the screen turns black (ingame) and a window pops up and it says

“Stonehearth Assertion failed” “Assertion Failed: new_node.name() == “mixins” ll new_node.type() == mixin_node.type()(C:/rb?ihome?root?SH-OB0-BUILD\stonehearth\source\resources\res_manager.cpp:657)”

the game kept crashing but when I deleted the folder and reinstalled it, it started working again.

looks like an issue with an mod :wink: mixins means that a mod adds something like crops and stonehearth cant get the infos.

mostly seen with old cookmods and brewerymods :wink:

I downloaded the mod ACE - GitHub - StonehearthACE-team/stonehearth_ace: Main Mod repository. Master is only assembled and updated by organization; unstable-work is used for assembling, coding and debugging.
I still get this error, how can I solve this problem?
