Dev build 160827-0457 x64 version hard crashes for me when playing SOD after opening the first door. This doesn't happen for me with the 32-bit build of the same version.
Stable (1.3.2) and older dev build (x64 160605-0724) doesn't crash for me either.
My OS: Windows 7 x64.
(this is my first time making a bug report, so let me know if I need to add more info)
