hello, items from the backpack are not active after you put them in the backpack, they are not picked up and cannot be seen

Well that is weird because i have been online all day picking stuff up from lootpiles and putting them in the backpack and taking them back out again to put into storage chests ? , and when i change into a radsuit i put my normal clothing in the backpack then change back into that gear when i go into cold biome .

there are few plugins on the server, no skins, no duels, there are quests. Sesver "KUBIK RUBIK" connect *.*.*.*:35900. Unfortunately, there is such a bug with a backpack.

Can you clarify what "are not active" and "are not picked up and cannot be seen" mean exactly? It sounds like maybe you mean they can't be held by the player.

Sometimes, when you take out some thing from the backpack (for example, a weapon), it is not visible in your hands, it does not reload, it does not shoot

I see. People have reported this before when using an item cleaner plugin of some sort. I'm not aware of item cleaner plugins being necessary unless you have another plugin leaking items, which should probably be the focus or your investigation.

Backpacks v3.5.0 now has an API method that item cleaner plugins can use to discover and therefore ignore the backpacks items rather than breaking them. Please inform the author of your item cleaner plugin so that they can improve it. Another option for them to consider is to make the item cleaner plugin temporarily unload Backpacks while it performs cleanup.
