I apologize in advance I do not know English and use a translator. My friend and I are playing a local game, we both have this mod and everything works, but when he throws me an object, I can't take it and it just lies on the ground. Help this is a mod setup or bug. Thank you very much in advance!

Do you have free space in the inventory and/or the hotbar?

Locked slots don't count.

Yes, even when completely empty

what other mods do you have?

And what is the server?

List of mods:
InventoryProfilesNext-forge-1.19.4-1.9.4
kotlinforforge-4.1.0-all-1.19.4
libipn-forge-1.19.4-2.0.6
OptiFine_1.19.4_HD_U_I4

The server is local

Can you update Inventory Profiles Next to the latest version.

Updated and still the same

who is the host of the game
other one the can't pickup items?

My friend is a host, he has the same mods.
We play together and that he and I do not pick up the things that we throw to each other.

OK
in the settings Mod Settings page disable locked slots

I ment in the first page named Mod Settings

and I guess you both need to do it

We set the same settings all without success

OK remove the mod and test if it works

closing due to lack of interest by OP
