Was going to continue working on a map, that I had just completed some areas in a few hours ago. When I try to load the map, the progress bar gets about halfway before quitting with this message:

Notice
Corrupt map: trying to load already loaded heat buffer. heat-pipe at {409.5000000000, -212.5000000000} is trying to load index 319 but it's already loaded for heat-pipe at {378.5000000000, -205.5000000000}.

All autosaves have the same issue, and were all created during my earlier play time.

Closest existing bug report I could find, marked as resolved: [0.18.4] Crash: HeatBuffer::HeatBuffer viewtopic.php?f=11&t=81141

In my current map, I do have nuclear power with heat pipes up and running, but those have been built and steady for multiple real-life days, and I've successfully loaded the map several times since then, until now. I've also successfully loaded previous save files without issue.

I investigated it a bit, and I think that the most probable cause of the problem is some random memory flip.
You will be able to load the save in 1.1.12 as the heat buffers get re-initialised at version change, but I suggest you run a mem/cpu check on your computer.

Thanks for taking a look at it! First major issue I've had over years of play.

edit: yep, opened fine in 1.1.12
