This weird green blot/blur showed up when I hit the materials overlay while I was looking if there was co2 in my base.
It was gone after a save/load game though.
I couldn't find the output_log.txt file
Building order near or after Pitcher Pump says unreachable, although there's nothing in the way.
I've seen this bug sometimes
It happened before with the save, the screenshot attached was taken just after a new game run/load.
