Blueprint Continuously being called in editor

I have a blueprint which seems to be stuck continously loading iteself after the game saves. Heres the log:

Those warnings continue (Currently on SpawnBuilding_C_53500) with no signs of stopping. This has happened a couple of times now and seeming started after I told the blueprint to destroy itself. Does anyone know whats causing this and how to stop it?
