At some point I had a picture of an Obsidian Golem appear and warn me about bothering him.  The game froze during his dialog, but eventually (30s?) started working again.  I hurried to save the game, and then exited and relaunched to try and prevent any issues.  Unfortunately I have one regardless - no units have a walking / movement animation any more.  If you move from one tile to another the unit seems to just appear there, none of the walking effects are being displayed.

The game seems to work other than this, but it's incredibly annoying and will likely get me to quit this game and start a new one.  Which is a shame, was having fun =\
