Greetings Clan-RmG-Team,
On your Battlebit server loading screen is proclaimed, that sniper classes are limited to 2 per squad. However during class selection it becomes apparent, that the limit of 2 is not configured for Snipers but instead for the Support. There can be 8 Snipers in a squad, but only 2 Support.
Please revisit your server configurations and either change the loading screen message to be accurate or fix the sniper limit.
Kind regards
SeseFeuerherz
