(BUILD 9972) error on starting new game

so i just updated my experimental build to latest version and make a new playthrough as usual. but when i made a new world and choose Custom Character, an error occured :

src/main_menu.cpp:779 [bool main_menu::new_character_tab()] Error: item group “mischw” already defined with type “collection”

it appears when the game loads some mods, Aftershock and Pk rebalancing.

I’m also experiencing this issue. I created a bug report: https://github.com/CleverRaven/Cataclysm-DDA/issues/35956

thank you… i was want to report this to github but such error usually has one or two reports coming up soon.

I have the same problem. but im not actively running those mods, the worst part is i thought it was because a major update, so i deleted my char xD

I hope to fix this error as soon as possible, this is definitely bad news for me:(

Also Modular turrets mod need same fix in item_groups.json at line 96
