Many have been already mentioned but for the sake of completeness here are the bugs I have encountered so far:
1) Sandbags and OKW Trucks place-holder shadow (semi transparent silhouette that tells you where the placement will end up) disappears if the placement is obstructed. Before 64 bit upgrade the faulty placement silhouette would have had a red tint.
2) Automatch screen takes to long to load (half a minute or so)
3) No leader-boards or player cards
4) Game crashes in mid game with no apparent reason (or I havent been able to identify one)
5) Unit symbols disappear (I had an opponent's shocks unit's indicator disappear once)
6) Automatch stops searching occasionally
Finally, this is a very complex game with a VERY complex code, so this list is very minimal considering the total level of complexity. I am sure these minor issues will be fixed in no time as well.
So devs at Relic, I think a "thank you" is in order for the hard work you have been putting into a game 7 years old. Keep up the good work guys!
Thank you!
