Sitting in Sherman on base trading shots with T34. VH is taken out then ord yet no sound of main gun or tracer rounds ibd. Another fellow was watching from the tower noticed same thing. I start rolling then I am taken out by a gv on base that I killed moments before yet no gv sounds of approaching vehicle. Pm individual who killed me said he had same issue when I took him out never heard or seen a shot. Now after a while everything seemed to start working as far as sounds go as more people showed up. Did not film have to put it down to some new patch issue.
