I get the following DEBUG: Missing item (check item_groups.json): iv_mutagen_troglobite
Impossible to dissassemble it as it just goes back to the normal map afterwards. May be happening with other items but couldn’t test it.
Just noticed this had already been reported by Cherry but according to that bug report it does disassemble as usual which isn’t the case here.
Savidiy fixed this one; I couldn’t replicate with the latest version. Try the latest experimental?
Thanks for the report though.
