Hmm, I've never actually crashed yet.
I did get my away team stuck underground a few times, and I get them stuck in random spots quite often. The one mission where you go in the Cave of Fire on Bajor was a nightmare, I was having to set a rally point and then remove it just about every 5 feet or my entire team would get stay where they were.
For ***** and giggles I'm trying to get 45 on my next character without spending any skill points. I was going to try with a klingon character, but their starting quest requires you to spend points. And you can't pvp or get to your ship before doing it.
