with the new research tree, i anlucked the Tier1 mortar, then i started using them to play (with all other squads at BR4). But no matter how much i played, the mortar squad did not get 1 single XP point. can someone help me ?
Restarting the game fixes this
Restarting the does fixes this, but doing this just refreshes the level of the squads, but them again the levels of the squads dont go up. so every time i want to upgrade my squads i have do quit the game and them start it again.
