Scaffolding Bug A18

I had started building the Blacksmith Town Template you unlock via campaign and hearthlings stopped working on it halfway through so I decided to ib the rest of it and just ‘destroy’ the scaffolding and ladders and now after starting my save back up I get this error Unknown #33501 | C -!

Steps to reproduce:
Irregular bug that can only be reproduced from a standpoint of a building that hearthlings abandoned

Expected Results:
No error
