stats only get saved when the server changes the map. did you leave the matches before that?
At least for me, the stats do not save approximately one out of five times, after the map changes. It is very frustrating.
It is not bad enough that I naturally suck at this game, but to continue to have valid stats not update after map changes is ridiculous.
TWI REMOVE THE STATS, if you cannot implement them correctly.
For instance, after a round, my rifle weapon leveled to 17. When the server changed to the next map, my weapon level is back to level 16. This happens repeatedly, with honor and weapons.
