Just tried to do fed minefield on my kdf and got kicked at start 10 times. There is a serious assigning player bug to a game for fleet actions i reckon. Please get this fixed cryptic. First Sb24 and now Fed Minefield. Whats next, stfs?
Since Cryptic/PWE don't seem to give a damn, I've figured something out.
Generally, the public queue sometimes puts you in an already-full instance.
You're being booted cause the instance is full (or has players zoning in and you got the short stick).
The temporary solution I've found is to just wait about 2 minutes and try again as spamming it doesn't work. Often it fixes itself for the '2nd wave' like at SB24. Sometimes it doesn't. Cryptic really does need to fix this issue.
