Similar to some previous bugs, the cybernetic combinator is causing a crash when its mode is switched. This time, it seems to be when it is set to anything other than the default Station mode, and is then switched back to Station mode. This is on a newly-created testing map. Deconstructing the combinator poses no problem.
The mod Project Cybersyn (1.2.3) caused a non-recoverable error.
Please report this error to the mod author.
