Welcome to the forum, @Luminous (I see you’ve been here for long, but it’s your first post).

Thanks for reporting. Do you have a savefile where this error is happening, or the building template that caused it? If so, could you upload them?

[Luminous]

I don’t have the building template or the save anymore because of the bug, but I can try to recreate the bug in a new save if you want. The engine error seems to be an issue with the scaffolding when I am building 2 story buildings next to paths or smaller buildings. The first time this error occurred, my Hearthlings had built scaffolding over an adjacent building and fallen asleep. After they all woke up they refused to build the building. I don’t remember when exactly the error message appeared during this.

PS Sorry for the delay, I’ve had trouble with this email and I’m transitioning to a new one.

[Luminous]

Do you think I should attempt the ‘repair game’ before going any further in case the bug is from corrupted files or something first?

[Luminous]

I have successfully recreated the bug, but the engine error has not yet shown up. I’ll fiddle around with it a bit. I’m also taking plenty of screenshots.
