MASSIVE issues with vehicle spawning. Don't forget at the start of the round where you are hovering over the vehicle spawn and then the map zooms out and everything has shifted. Sometimes this results in you spawning as infantry even though there are still vehicles available.
THEN if you do get on the available vehicle you can't select it (as mentioned in the Original Post). You have to go off and on to the vehicle multiple times and sometimes lose it.
THEN sometime you are first onto a vehicle and are trying to select the model you want - and it's scooped out from under you.
THEN when you're trying to spawn on a flag to get an "available transport vehicle," there are none there even though the map shows they are available!
MADDENING!
