In 1.0a every time I finish a game whether it's winning, losing, or even abandoning a run, the game crashes. This wasn't a problem in 1.0. Using "vulkan" with Intel HD 4000 gfx, on an up-to-date Arch Linux. Here's a crash log, I can post more if needed.
It may be possible that the crash is unrelated to upgrading to 1.0a and just a coincidence, but unfortunately I don't have my 1.0 installer any more.
