Thanks for the feedback, as always. Just to focus in on a few key points here:
The "assign new research" issue is a bug, and it doesn't usually happen. If you have a reproduction case then please post it in the bugs forums so we can fix it.
One of the camera issues is a bug, the other one we'll turn into an option shortly.
There's clearly an issue with the Cleaner missions if you didn't get any after day 55. There's meant to be a mission spawning on day 68, and there's also a Scout on day 62 and two Destroyers on day 74 (one of which should spawn near your base). Had you started building a second base at that point? Maybe it spawned near your secondary base before you got it operational?
EDIT - oh, actually, there was a bug with that Destroyer mission. I'll fix that.
