My first post on the forums: what a great game this is!
I’ve been building a bit around and encountered an ugly bug.
When i’m building a multi-floor building (4 floors), the lua lag is tremendous (like, 99,9%) as soon the Hearthlings start to work above the second floor.
Log is included here.
(edit) Interesting is that the lag disappears instantly when the hearthlings do something different than building on the subject building. the lag/freeze reappears when the build continues.
