[Feedback] First time player in beta

Yesterday night i got a little spare time and decided to give a try to Entrenchment beta 2, the game runned smooth for about 50 minutes until it minidumped while toying with a mine while a IA fleet was plundering a planet of mine

Only flaw i could notice apart from the minidump was during a planet assault, IA was again plundering my planet and i decide to build a SB, just after the build mesh loaded on screen it started to show fire effects and the attacking fleet just runned away , the fleet was composed by a Dunov and several and varied frigates, as afar as i can remeber.

The map was dopplehangers, with four player 3 TECs, me and two IAs and one Vasari IA, all IAs were set to hard and normal game settings.

Excellent addon to normal Sins, i´m eager to end my examns to be able to devote more time to explore this mini expansion.
