Switching class mid-match doesn't seem to change endorsement

Hi,

When I hit "V" after I die in a match, and click a new custom class, then click Join I join the game but the endorsements on the right side are still my old ones. (I'm trying to have 2 tank load-outs)

If I just double-click the new class, it will show the map, the rest of the interface disappears, and it seems to hang. Sometimes I get re-joined, sometimes not so much.

It seems the old endorsements are in effect too (like it's not just a display bug, I'm actually not switching.)

Am I doing anything wrong? Is there a bug?

Running: AMD 3-core Phenom, ATI HD4870, 6GB RAM
