[SOLVED] [1.15.2] Item not writing to NBT on first use

[Novârch]

I've made a custom item that stores a player's capability in it's NBT. The item works fine except when I use it for the first time it consumes the player's capability(resets it's values to 0), but doesn't store it. All subsequent uses of the item work flawlessly.

Here's a link to the item's class on GitHub.

 

Edit: Solved by updating the NBT tag twice, I have no idea why this fixed it.
