I get crashes at any time but usually after maybe 30 minutes of play although sometimes sooner or later. Then I have to start the whole level again. This is very frustrating and means I have been trying to get through Teotl II for weeks now. Is there any way of saving progress within the level so I can continue easier?

This happened to me a few times, but only in survival mode. There is no way to save manually, unfortunately...

Well I have accidentally found out how to get into the console. Only some of the commands seem to do anything though. One command is quick save but I'm not sure exactly how it saves and I can't seem to make it work anyway. Anyone know?
