When I was joining the server getting on security, I was met with the error message "Battleye Initialization Failed" even though I was on the server 5 minutes prior on civ. I tried restarting my game, same issue, restarted my computer, same issue, tried disabling and then re-enabling Battleye, and still had the same issue. Then I tried joining another server and had no issue.
Is there a fix to this or am I just going to have to wait till server restart?
Try verifying your game files by heading to steam library, right click arma 3, properties > local files > verify integrity of game cache. It may take a while considering arma is a large game, or depending on your HDD / SSD / Internet speed. This will repair arma, and download any missing files (in your case, possibly the textures / objects).
