After playing the Entrenchment Beta 2 for several hours, as the TEC, here are some of the errors I've encountered:
1. Once, after loading a saved game, I noticed that the Advent Starbases appeared black.
2. Excluding the Vasari, Starbases don't spin unless they are engaging the enemy. I don't know if the spinning is intended or if they are supposed to be stationary. Also, if I zoomed in close to the starbase, I noticed it moved slightly back and forth.
3. I noted several crashes for which I couldn't find a cause.
In addition to these errors, I feel that the Torpedo Cruisers of the TEC should be weakened slightly.
Overall I am enjoying Beta 2
