I've seen quite a few cases lately of completely ruined squad defence games, where the defence spot, the spot where the bots run towards marked by a shield on the map, is way in the middle of no man's land instead of in the trench. This means that the bots won't approach the trench at all, making the game completely useless. Also, please don't forget about the "No XP gained in squad defence" bug, which is an even greater problem than this in my opinion.
I'm not sure if it's only there, but I've seen this in the Vosges map.
