As video shows I have 2 grenades in my inventory, after I put them on the ground, I'm able to throw yet another grenade.
Also sometimes the weaponholders created by placing items on the ground become inaccessible. i.e. no action appears. Logging out then back in makes them accessible again.
Log into dedicated server and place items on the ground.
interesting.. dupe items through clicking at same time on two machines is one thing(which takes at least weeks to find out a proper solution), but this one is a stupid bug which has to be fixed asap. I promise, that I will take a look tomorrow and will bring a fresh news.
@japapatramtara The ticket is exactly 3 months old. Retested it today, the dupe doesn't happen any more. Close it if you want.
