I have the same problem. It worked fine with 0.25, but with the new upgrade it crashes continuously. This is completely stock, no mods present. The logs for the crashes are available here I've tried reducing the graphics quality to see if that made any difference, but it didn't appear to. I'm using a late 2013 15" MacBook Pro Retina, 2.6Ghz i7, 16GB RAM, GeForce GT750M 2048M, running Yosemite 10.10.1 Any advice on being able to keep playing would be much appreciated!
