Non-depot building was selected as depot

I have the following error:

(Filename: C:/buildslave/unity/build/artifacts/generated/common/runtime/DebugBindings.gen.cpp Line: 51)

Simulation error: Non-depot building was selected as depot! Actual AI type: ShelterAI

Will try to investigate what actually causes this - if you have any suggestions how I can do it let me know. The error pops-up every few seconds its hard to investigate.
