Group of unknown size, at least three, likely cheating via duplication hacks or other methods. They seem to be destabilizing the server. After being killed randomly, my partner in the game came across a perfectly organized stash of kit. Matching camo, VSD, M4, lots of mags and ammo. We have reached end game before and never had this level/quality of kit. Matching clothes, vests, etc., in the snow camo pattern. As a freshy he grabbed up the kid and shared it with me (also fresh). We then began experiencing lag, kicks, weird anomalies, etc. About an hour later we saw three players in the distance with scopes (300m in game or so) and they had the same looking kit with the same rifles, ghillie wraps, full tactical gear, etc. I think it highly doubtful a loot restricted map like Sakhal can produce such players. Last night we experienced instability, heard a surprising amount of gun shots, and experiened weirdly high and unsual (never happened in three years on my home network) pings that would come and go. We just logged off tonight after getting kicked out to the login screen every couple minutes. This exploit seems knew and seems to affect the server. After I would get kicked the half full server would have a queue indicating 3-5 people were also kicked at the same time. We played this server off and on for a few months, never encountering anything like this, and we spent out time avoiding these guys that are moving fast, with matching gear, and shooting more and throwing grenades more than anything we have experienced before. Could they be that good? Sure, but all the matching kit looks like duplication. The game grew unplayable and we logged off. I am marking these likely exploits as major as we are likely to abandon the server after tonight.
