OK, I was playing a map with only a few people on it. After I capped the intel, I noticed that the teams were massively skewed. So I swapped teams. Problem: I still had radar coverage on the enemy team, until the radar expired for all. So I swapped from Green (capped) to Blue (didn't), and had green guys on my radar.

Something to be fixed?

Ingame, you also can throw grenades over the 'end' of the map, which actually is another edge of it. In that way you can destroy those bunkers, which are built near the edge.

Both of these are seconded though.

Interesting
