Earlier today I was playing a random generated small map online MP and noticed a few bugs. I don't know if these have been reported before, but here they are.
1. The game froze for about 5-10 seconds and when the game continued to play I lost all sound for about 15 seconds. It happened fairly early into the game (15 min in) so there were no fighting with large fleets, which rules out lag. Especially because later when large fleet fights took place there were no lag.
2. I could not select my ships by clicking on the owned ship tab to the left of planet my ships were in. This happened a few times, but not every time.
I hope this is enough information to help you out and I would like to point out that this was my first online match since the Betas were released.
