Updated to the newest version. Found a problem that in SPH/VAB if i press control+z to rollback, IR's configuration windows instantly mass up, unable to response, gives me a white blank page while my mouse move over the window. QwQ could be temperately solve by exit and re-enter SPH/VAB, but everytime i rollback it just get into trouble....... And after been playing for a while i realize i got into whole bunch of troubles...... Really, how could this happen? seems rotation/extension limits isn't working at all, things just keep rotating and flying around..... seems epic though. hmm, the light just fly out of the rail.......... where it wants to go? And for this, i am pretty sure i set the a rotation limit from 0 to 90, but well, it danced over 720 degree already..........
