I've been reading this thread for quite a while so I first wanted to thank people who've posted for all the great idea's. Currently on my 8th attempt and I'm about halfway through the book now and no longer panicking, thanks to those idea's.
I finally decided to sign up and post because of a bug that has crashed my game. Luckily it hasn't corrupted my save, and I've been able to restart the game and create the bug several times now.
I was about to make a bunch of thermal expansion machines and needed plastic sheets for the machine frames, since I have so many pieces of plastic from an afternoon of pneumatic's I decided to use those to make the plastic sheets. Using the 2x2 inventory crafting grid, when I attempt to use the grey plastic from the burst plant seeds the server shuts down as soon as I as the last piece falls into place. I've tried it with all the other plastic I have available (fire, rain, lightning, propulsion, repulsion) but the only one that crashes the game is burst plant plastic.
The crash does not happen when I use a crafting table/station.
