I thought I'd try and help out by beta testing this release, even though R64 is OK for me, and got the following crash when closing, straight after saving:
---------------------------
Construct 2 Check failure

Check failure! This is probably a bug:
Failed to remove directory '05BD21F0' (145)

Line: 89
Function: __thiscall Project::~Project(void)
Build: release 64 (32-bit) checked
Component: Construct 2 IDE
(Last Win32 error: 145)
