Movement speed no longer working

Describe the bug After the spigotmc update, the movement speed doesn't seem to work anymore. Tested on localhost with this HUGE_MOTHRON_WINGS default armor provided by the plugin. Checking on /exploreattributes, and the movement speed doesn't seem to change at all

To Reproduce Steps to reproduce the behavior:

  1. /mi armor HUGE_MOTHRON_WINGS
  2. equip
  3. run

Expected behavior Movement speed should be affected (slower in this case)
