[New Builder] New template bugged out – Now two older templates are merged together + Windows Error Message

Saved a template in Release 815 that couldn’t be placed afterwards. If I then try to place an older template instead, it’s actually two templates overlapping.

I’d upload a save but I reckon it won’t help too much without the templates. Don’t know where the new ones are stored. Would gladly provide it, though, if still needed. No mods used.

Edit: Got an error message from windows for a change. Happened upon trying to place stairs when there was already one stair block placed.

Accompanying Stonehearth error message:

Probably related to the fact that the walls of the last building overlap the overhanging roof of another building.
