Describe the bug
When using experience pump upgrade options it won't take player's exp while storaging in tank upgrade.

To Reproduce
Steps to reproduce the behavior:

1. Open backpack with experience pump upgrade and tank upgrade while having some exp in player
2. Click on "Store X levels" or "Store All Experience"
3. Tank upgrade fills with EXP but EXP also stays with player

Expected behavior
EXP moves from player to tank upgrade and is no longer on player

Screenshots

Versions
Tried with Sophisticated backpacks 1.21.3.20.18.1117 and 1.21.3.20.26.1151 with neoForge 21.1.73

Sorry, my bad, I didn't test it with sophisticated backpacks only.
I tested with all other mods in our pack and the problem shows up with Corail Deconstruction Table.
So, complete setup to replicate the problem:

• neoForge 21.1.73
• Corail Deconstruction Table 1.21.1-485
• Sophisticated backpacks 1.21.3.20.18.1117
• Sophisticated core 1.21-0.6.46.724

Yup, their vial item code overrides the xp I am taking from player with 0 so it ends up taking none. No idea why they're doing that and you will definitely want to report to them as I feel that code should do nothing when I am not even using that item.

I am unable to recreate so I guess you have another mod in the pack there that's messing with experience as well. If you can figure out the smallest modpack required to recreate I can check with that mod (those mods) if there's anything wrong that I should fix.
