[1.20.1-forge]-Epic-Knights-9.8.jar

this encompasses both weapon and armor mods

when on a solo-world the mod loads up just fine, every time is labeled as is and nothing seemed to be out of wack, how ever when i load into a multi-player server with a friend, the creative tabs for the mod all end up labeled as "minecraft:air" and proceed to crash the game when ever loaded, and recently we found a chest with one of the dungeon weapons, and upon opening it it seems to crash the game because of this issue, afaik personally.

Expected Behavior

All mod tabs should be loading properly, names of every individual item working labeled properly with stats and usage, how ever every item is an unusable item labeled "minecraft:air" while still maintaining the visual sprites and enchantment sheens, game crash when tabs or items are loaded in any way.

Mod Version

9.0.4

Minecraft Launcher

CurseForge

Operating System

Windows

Custom Modpack

Additional context

Items are Air Issue

@Kajiyaa Well, that's definitely a first. So, there does seem to be a discrepancy between the mod list you posted and the mod list from the log. Are you sure that is the correct log? According to the log, your mods are as follows:
