Describe the Bug

So I didn't have a chest nearby and wanted to put my contraption away for a while. I'd like to point out right away that it was almost empty.
So I stowed it in an iron backpack of sophisticated backpacks.
When I came back and tried to take the contraption again, I got a payload error.
I tried several times and emptied my entire inventory, including the armor, but I kept getting this error.
Funny thing is, I could put the whole backpack on and nothing happened. I just couldn't get the contraption off.
I finally solved it with a good old funnel. Minecraft version 1.16.5 and the latest possible version of Create

Reproduction Steps

1. make contraption with chests and store anything in it
2. put it into some backpack from a sophisticated backpack mod.
3. try to take it back into your inventory (1.16.5 Minecraft)
   ...

Expected Result

Since there is no problem with vanilla storage, I guess the backpack mod is to blame. Might not be a bad thing to try and look at it, as the backpacks are otherwise great.

There are 100 others, but they shouldn't interfere because I wasn't using any non-vanilla stuff at the time.
Maybe inventory tweaker

Additional Context

No response

Well thats likely nbt overload protection I would assume

Probably. However, I was wondering why it wasn't happening with normal vanilla chests. Is there any chance of this not happening with these backpacks in newer versions or that it won't happen? It's not that big deal, more of a minor annoyance.
