Name tag causing crashes

We noticed issues with the way the game handles certain characters in steam game tags used ingame. Our team tag is [AH!]. When in a ingame squad, neither the player with the tag nor the other members can see the name. It appears as a empty entity. Whenever we change leadership, remove squad members, join squad during match or just leave the squad, it results in a crash for all squad members. As a test, one of us removed the tag and no crashes accured anymore.

For clarification, my full game name was [AH!]ferdiniouS and changing it to ferdiniouS has fixed the issue for me.
