Regarding the numbers of bosses in mission, we ran into some very strange numbers tonight.
We had a mission called 'catch electronics thief' (not exact wording), a level 22 freakshow mission. We had 4 people in the team, the mission difficulty was easiest, Hard Boiled.
The mission included approximately 50 freak tanks, which were definitely not mentioned in the briefing.

There were maybe of total 10 minions and lieutenants in there, the rest were bosses. How do I know the total of tank numbers? My tanker had never faced them before and the tank badge meter was almost exactly in the middle of the slider afterwards. All the tanks were level 22 or 21.
This is not normal, right? Don't get me wrong, it was a fun mission, but it could've been a total suicide as well.
