What's happening is when the bipod is selected, I always have to put it down after spawn/respawn. If I get revived, it also goes back up again, and I have to put it down again it does not stay down. Even after I die if you look at the gun thr bipod is back up again. I'm not sure if this is a glitch or on purpose. Because, I thought if the bipod is up and not deployed you get more hip fire?
As for the for the fire rate, I'll have to wait for it to happen again to confirm. But, yes it changes automatically to single shot after I die and respawn. I play on PS5 so I know it could be accidental. But, I tested it before and remember it was not accidental. I've just learned to put up with this type of 💩 for long lol.
