#1 and #4 both happened to me and are quite annoying.

I've never personally witnessed #3 but I've heard chatter of it happening. Taking 20 mins to beam up and back to ESD seems excessive and I'd suggest running a force verify from the launcher client.

#2 actually isn't a bug (at least from what I read in your description) -- those are daily fleet actions and they're randomly chosen. Thus it's possible that Klingon Scout Force just won't be the daily for sometimes two weeks. The PvP daily is the same way -- you may get arena, capture and hold, or war zone, but there's no guarantee you'll get a particular one tomorrow, or the day after that, or the day after that.
