Error when using the Lunch Basket and interacting with the Slots; it takes me out of the world as if

[knotty trench]

When using the Launch Basket and scrolling through the slots with the mouse wheel, the game crashes and I get a message as if I were on a server. I checked with chatgpt and it says that Supplementaries is trying to synchronize a "slot reference type" and NeoForge is rejecting it, which is why the internal server is crashing. Here's the crash log. This is all happening using the latest available version of NeoForge, 1.21.1.

Are you using latest?

On cf

[knotty trench]

Yes, the version supplementaries-1.21-3.5.27-neoforge.jar

Wait, I just saw that there's a newer version on CourseForge. I haven't tried it yet; I use ModRinth for convenience. I'll try version 1.21-3.5.28 and get back to you
