Missing guns and double click for actions [REDSEC]

These bugs are happening almost every redsec game, what happens is i try to collect an item and i have to double click for it to happen. And some other instances there were guns missing from the ground when they were right there and no one stole or picked them up, they simply disapear from the ground... Also please buff tank sound. i was close to a tank one day and i couldn't even hear it
