I had previously pasted the ghosts and was returning from a quick trip to get more materials. I probably used the jetpack to return to the area where my plant was being built, but I do not remember if I had deactivated or reactivated it near the time of the crash. The primary items being placed at the time were heat pipes and condensing turbines. I believe all of the heat exchangers had been placed previously.4841.986 Error HeatBufferManager.cpp:368: Didn't record all update indexes: 14 != 15.
I briefly tried to reproduce the problem but was unable.
The full log is attached, and I put the most recent autosave, mod list, and dump at https://www.dropbox.com/s/iunxnpc3cmul2 ... h.zip?dl=0.
Edit: heat exchangers, not boilers.
