Gonna +1 this. I caught a similar fatal error the moment I plopped one down in a lab scenario:
The mod OSHA Rocket Silo and Container Signals (2.0.0) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event osha_container_signals::on_tick (ID 0)
Entity is not rocket-silo.
stack traceback:
[C]: in function '__index'
__osha_container_signals__/scripts/functions.lua:92: in function <__osha_container_signals__/scripts/functions.lua:3>
The active game crashes back to main menu when this error occurs.
