On my server I'm finally making the Gem armour from EE, but some of it doesn't work properly. The explosion and the fire resistance of the chestplate work fine, but the movement abilities of the boots aren't working properly (Yes, i have turned them on). When i hold space, i rise up into the air very slowly, but after about 3 blocks i can't fly any more and slowly go down. The sprint ability doesn't work at all. I've heard of people having similar problems before, but i can't find a solution anywhere. Any ideas? I have gem armour enabled in the config, and flying is enabled on the server
