Looks like it crashed in the new surface code. See below for files. I had just created four sheets, selected just the mutable part, and hit "5" (idealize), and was moving it away from the fixed part when it crashed.
log.txt edited to just the tail.
1916 crashed in the middle of me creating sheets with the BluePrint tool. Now, every time I try to re-load 1916, the game crashes. I don't know what or where all that gibberish is in the attachments in Greg's post, but it is clear I am having the same problem.
My log.txt file has this line, repeated hundreds, or even thousands of times:
core.conformation.Conformation: [ WARNING ] missing heavyatom: OXT on residue VAL:CtermProteinFull 81
I made the necessary changes to the file names as suggested in chat by bkoep. I was able to re-start 1916, but it again crashed in the middle of thying to create sheets using the Blueprint tool. I am dead in the water.
Thanks guys. 1916b released and fixed the crashing :D
