Describe the bug (yes i'm going off the default thing, hush)
basically me and someone i know were able to dupe or craft with my backpack and the crafting upgrade

To Reproduce
Steps to reproduce the behavior:

1. p2 opens backpack on p1's back
2. p1 puts a crafting recipe in the crafting box, putting the output item in its slot
3. p2 takes the materials out of the box, which should take the output item out of existence, but for some reason it seems to only be done locally
4. p1 gets to take the output item out without actually using the items required to craft it
   (note: you can do this while switching p1 and p2 after step 2)

Expected behavior
it's meant to dissapear for the both of them if you take the items out, right? so why does only one person lose the output item

Screenshots
If applicable, add screenshots to help explain your problem.

i forgot to note that step 2 only happens to p1 locally too and p2 sees the image above

this image above shows p1's perspective inbetween step 3 and 4

Versions
the mod's called sophisticatedbackpacks-1.18.2-3.20.2.1036.jar with it's dependent being called
sophisticatedcore-1.18.2-0.6.4.604.jar, it's called the same on the on the server, that's the best i can give you in this part right now

wait this bug is already solved, link to the earlier issue is here, the bug's that i guess, maybe i'll find the magical 1.21 version with the bug gone

the earlier issue report was in 1.20.1, while mine's in 1.18.2, which is an issue of itself for the dev(s) to deal with, to fix bugs in all of the game versions, which they can also fix just in the latest game version,
but i guess all that does is kinda make bugs features in later versions, oh well what can i do now
