Thanks so much - I can confirm I've been able to access it now and I'll work on it after work today. I've got some routines written that are doing analysis of bottlenecks in the code (I've got a bot that can randomly play the game to test this stuff) so I'll assess the results later on. Really appreciate all the trouble you went to sharing this file - it's really helpful.
Sorry for the lost messages - that really sucks. Rest assured all your bug reports are in transit right now and will appear in the next patch, and in the devnotes. And the quality of life / visual polish stuff too e.g., the floor tiles in dungeons. I'm on it :-)
