I have two issues, one recurring and one new one:
The new issue is that for some unknown, unannounced reason the game just crashes to desktop. I've checked my Event Viewer in Windows, but no error messages can be found on this; the game just stops, even if I'm in the middle of a game.
The recurring issue is somewhat the same, as it is that the game just randomly kickes me out with a "Server is temporarily unavailable, please try again later" message. I try to log in several times after but to no effect. I've seen this issue pop up on the fora since the game launched, but after every patch this issue still lives.
Are these issues known (and being addressed)? It really ruins the game experience (and my grind for XP, money and unlocking ships).
To end on a possitive note: I like the new leveling system and the XP that I get per game in relation to the module cost. leveling goes reasonably fast and working my way up the Jupiter Arms tech tree for the dreadnoughts is fun.
