Why, after entering the server, all things from quick access end up in the inventory? How can this be turned off?

gradually increase this setting until it stops happening

Can't it be completely turned off? there is no such function?

you can always uninstall the mod

No, the mod is great, I just don't understand the meaning of this function. Why is she needed

I understand. Thanks a lot for your help. Prosperity modification.

as you can imagine I've put that setting in because it's needed

The problem is the server is not behaving as expected and breaking the mod. So the setting is there in case of bad server behaviour to make the mod compatible.
