I managed to crash the game with this mod by cutting ghost of smart linked chest. Construction bot was on its way to deliver the chest.

4154.286 Error MainLoop.cpp:1391: Exception at tick 233370: The mod Kuxynator's Smart Linked Chests (2.0.9) caused a non-recoverable error.
Please report this error to the mod author.

I also had crash when copying ghost chest's blueprint. Not sure if related:
