Using monk-mod-1.1 in a modpack on Forge 2655

Player (LV 19 monk) got kicked from MP server. No crash, but the player can't re-join because the server throws the following exception on every login attempt.

Ah, it looks to be an issue with someone having 2 potion effects. I only tested the code with 1 potion effect.
