Thanks for that OP. I sent the 1st one to QA to log it properly.
For the 2nd one, it's not a bug but a really low chance unfortunate event.
Your team got the sector EXACTLY during the 2 seconds you were out of combat area.
During breakthrough, if you are in the combat area, you can move freely to the next one when a sector is taken but since you were outside exactly at the same time you took the sector the game considered that you where outside (which was the case) so you kept being outside since the game sectors moved forward.
