When Blood Magic is installed, players are slowed down instead of sped up by another mod that changes walk speed. This is what I'm doing: https://github.com/DivineRPG/DivineRPG/blob/master/java/net/divinerpg/utils/events/EventArmorTick.java#L212

How? I'm sorry but you'll have to find the reason why first and if you can, a way around it before reporting it here.

Seems to be caused by this. Not sure why that's there, it doesn't seem to be doing anything other than setting the player's speed to the default value.

Next push should fix it
