[KIAI-325] "/xp add level" does not work correctly
If we take a hypothetical situation where you need to have 672 xp to increase your level, then for a person who has 609 xp, /xp add level 1 adds not 1 level, but, as in this case, 3. At the same time, if a person has 0 xp, then /xp add level works correctly.
