Helloes!
I played a game @ IC yesterday and noticed two major bugs in particular.
1. There was a bug with spending credits/resources - sometimes when I clicked on a research, built a ship, built a structure or anything else similar - I was often charged either the double or the triple amount of the real cost - by cancelling I sometimes got double/triple money back - meaning anyone could sit and spam this exploit to get wealthy in notime. Sometimes though the money was permanently lost, even if you cancelled your order.
2. Starbases weren't upgradeable at all - you could click the upgrade icons, but no progress-bar was appearing - reneding them basicly useless 
3. Planets showing "bonuses" prior to being explored (not sure if it's supposed to be this way in the expansion or if it's a bug) 
Sincerely
