turned out, i didnt know the new way how to enlarge this industry zones within the bigger zones yet... thanks anyway

@Lionpudding I have don't know why that would happen, this assets should be just the same as the ingame level 1 farmhouse. Perhaps it's an issue with any installed mods of yours. I have uploaded another version of the farmhouse (link in the desciption), you might want to use that if it keeps happening.

Something wrong when i use this building. I placed it in an farm area, it creates a new zone itself inside this zone then. you cannot place fields around it. and if i bulldoze the building its own little zone stays there and i cannot erase the zone. after trying a few more times i got a lot of little zone which i cannot delete anymore, so i had to reload an old saving. do you have an idea why this is?
