Trying to Build and keep getting Engine error

I am building a big building and I got pretty far in it and then as I try to build I keep receiving this engine error:
release-707 (x64)
radiant/modules/entities.lua:317: attempt to index local ‘entity’ (a nil value)
stack traceback:
[C]: ?

I want to finish this building, Can someone please help!

hey there @Voltex, welcome to the discourse :smile:

would you be able to provide your savefile that has this bugged build in it? To upload a save,

locate the folder in C:\Program Files (x86)\Steam\steamapps\common\Stonehearth\saved_games (assuming a default Steam install), zip the individual save’s folder (not the entire saved_games folder), and upload it. If the *.zip is less than 10 MB, feel free to upload it directly to the Discourse. If larger, please upload it to a cloud storage site like Dropbox, Google Drive, File Dropper, etc. and post the sharing link here.

Here is the save file. (5.0 MB)

i am having the same problem this just keeps poping up and every time i try to build something else it wont do anything

I found a kinda solution to the problem, i had the same problem, and the engine error is still there, but you simply just detroy the building you are building, and then you place the same building afterwards :slight_smile:
I hope this will help you
