Stackrefill bug on multiplayer server (including video link)

[CuNe89]

Minecraft version: 1.20.1 Modloader: Forge Forge version: 47.0.35 Environment: Multiplayer

Mod name: Stackrefill Mod version: 1.20.1 - 4.0

Hey! I have discovered a bug with the mentioned version.

This also occurs only once I am on our server. In singleplayer the mod works just fine.

We have a paper server, which loads the mods in through Forge.

Other mods we use on our server are:

Xaeros-Minimap-Mod-Forge-1.20.1 World-Map-Mod-Forge-1.20.1 worldedit-mod-7.2.15 OptiFine_1.20.1_HD_U_I5

and of course for stackrefill to work collective-1.20.1-6.72

Also, I have already discovered an almost similar one here in the open tickets, but the person has not answered further. The mentioned ticket was from March 26 this year from user: DaisyDumm.

Here's what happens: When I place the last few items of a stack (while I have the rest of the stack in inventory), nothing is placed in the hotbar from inventory and the stacks in inventory are invisible. As soon as I click on the place where the invisible items are, they become visible again.

I have also recorded a short video to better illustrate the bug. The first scene is from my singleplayer world, the second from our server.

I would be interested to know if it is a general bug or if there are problems on the server side.

Can confirm it too, as showed in the video

Same here on 1.20.6 with the following mods. Singleplayer works but Multiplayer doesn't:

We have a paper server, which loads the mods in through Forge.

I'm a little confused by this part. Do you have a Paper server and Forge clients, or some kind of Paper+Forge hybrid server? Is stackrefill installed only on the server, only on the clients or both?
