Same thing with 2 of my servers, and I called EA as well. Same resolution.... we don't know. It has to do with this second batch of servers because I have 3 and the first one came from the first batch and if u change settings it shows normal preset on server info, the other 2 show unknown preset forcing me to have to run them in official which is not what i want to do, but have no choice. There is a problem with the second batch of servers. It happened at a random time they were working finwe in beggining then boom next round both switched to unknown preset and servers started emptying.
