At the moment i am trying to create a megabase that is capable of supplying a compressed blue belt of tier 3 modules. I do hope that i will be ready before 0.15 is out, because then i want to make a mega base that focuses on research.

I also experienced this crash, i saw more threads about it on this forum but this one was on top.
I got the same crash and it seems to come from shift right clicking fuel into the ingredient slot.
