When I start/open a world I already played on the structures in the village I'm currently in regenerate.
By regenerating they also delete already placed blocks - lost an oven to this ^^
Regeneration also isn't clean but stacks
Closing and opening the world is enough to trigger this beahavior, don't need to close the whole game
versions:
Better than wolves ce 2.1.1
craft guide 3.0.1
deco addon 4.1.2
For some reason one drive saved/synchronized the whole multiMc-folder. Even though I'm pretty sure I excluded it from the folders for synchronisation...
I guess having two diffrent programms manipulate level.dat and stuff like that just corupted my save.
I excluded the folder again. If I encounter magicaly regenarting buildings again in the future I may open a new bug report but for now I'd say this one can be closed (probably).
