/xp issue

Hello,

I noticed some strange behavior with the /xp command when testing at very high levels (around level 1000).

• When I set the xp points to 4 and then run /xp add 1, the value stays at 4.

• Only after adding another 1 point, the value updates to 5.

• Later in testing, when I reached 604 points by repeatedly adding 1, the value suddenly jumped by 2 instead of 1.

It seems like the command sometimes ignores the first addition or rounds the values in an unexpected way. Is this intended behavior due to how XP is stored at high levels, or is it a bug?

Thank you for your help!

Best regards,
Piotr
