Describe the bug
crash.txt
Game disconnects me whenever I open any backpack. I can create a new backpack and still get disconnected. Error message shown in game: Internal Exception: java.lang.runtimeexception: Tried to read NBT tag that was too big; tried to allocate: 2097153bytes where max allowed: 2097152.

If it helps, I can also provide my world folder.

To Reproduce
Steps to reproduce the behavior:

1. Open backpack
2. See error

Expected behavior
Bag to open.

Versions
FTB Skies 1.06. Mod version that you're using. Version of forge may also be helpful in some cases
Sophisticated Backpacks 1.19.2-3.18.43.801
Sophisticated Core 1.19.2-0.5.47.234

Looks like you have put something with way too much nbt in your backpack. try placing that backpack in world and get stuff out of it using pipes or hopper. Most probable cause I would say is create contraption or something similar

already tried that. Even if I make a new bag my games kicks me out.

ok in that case could you share your sophisticatedbackpacks.dat file and UUID of your backpack? (visible with advanced tooltips). if you can't even view that uuid to take screen of it then I would need your playerdata. Basically the only way I can see what's going on for you here is by going to the data saved and seeing what data you have saved there.

Here it is.

sophisticatedbackpacks.dat.txt

UUID: 251b9fcd-eec4-4b19-b8ef-f1d3d1d341a9
06a2937e-6d78-4147-ac53-1d6160840fc0.dat.txt

So there's nothing wrong with this file - backpack contents nowhere close to max limit. could you also share sophisticatedbackpacks_settings_templates.dat if you have used the functionality of saving memory slots it could have that data saved there and potentially have an item with way too much nbt

I don't have that file. I don't think I've used saving memory slots or any filters.

ahh, I can see what's going on - you have armory cabinet in your inventory with a ton of items and all of that nbt needs to sync with that bit of backpack nbt probably tipping it over the edge. try removing that from your inventory and you should be good.

That is exactly it. Thank you for the help.

ok, glad that worked, I was getting worried there's some hard to debug issue with backpacks
