The error down below happens when using the /ctron command from Constructron-Continued but posting it here as its this mod that's throwing the error
the command used was "/ctron disable construction" but it happens with others too
Error while running command "ctron": The mod Rail Signal Planner (1.2.5) caused a non-recoverable error.
Please report this error to the mod author.
