Build 8595/6? breaks things

I use the game launcher. After the latest update I tried to go near a cemetery and crashed- I see logs for an 8595 mentioning some cemetery changes but it’s not available for download in the launcher, so I’m not sure which broke what. Error reports below are for build 8596

Debug throws some complaints about mushrooms and cemetery tiles on world load:

DEBUG : seed_mushroom_magic in inline_recipe_summon_mi_go is not a valid item template

FUNCTION : void component::check_consistency(const string&) const
FILE : src/requirements.cpp
LINE : 318

DEBUG : seed_mushroom_poison in inline_recipe_summon_mi_go is not a valid item template

FUNCTION : void component::check_consistency(const string&) const
FILE : src/requirements.cpp
LINE : 318

------------One of the errors involving cemetery tiles--------------

DEBUG : invalid overmap terrain id “cemetery_4square_00_south”

FUNCTION : int_id generic_factory::convert(const string_id&, const int_id&) const [with T = oter_t]
FILE : src/generic_factory.h
LINE : 380

must be one of those mods that require mushroom seed to summon mi-gos… first one is invalid item template coding…

second one is invalid mapping id for the cemetery… serious issue here.
