I have found a couple minor bugs in the game. Sometimes, the loading screen does not properly display the image of the particular map I am playing on (this typically happens on Evac HC). Also, in Hardcore mode, the map is supposed to be shown when someone on your team gets a mortar strike or sonar. However, sometimes the glowing support icon is shown, but the map will sporadically appear and disappear on a whim.
These are a couple bugs I have encountered while I have been playing. I apologize in advance for ambiguous statements that I may have posted.
When deciding whether to stay or leave, if you type "Yes, LDAC" instead of just "Yes", it will output "LDAC is my name", and then it will make you choose whether to stay or leave all over again.
There seems to be a bug where the server capacity reports are inaccurate. A few times, a server that seems to have an empty spot is, in reality, full, and the player has to wait or switch to another server. Another thing I noticed is that the 'M' key fails (for me, every time) when I want to join a team as a spectator. The game is great, but these small bugs make the game a bit frustrating at times.
