Steps to reproduce

Equip multiple movement speed bonus items. For this example I used Danzo Sun-ate +12% Kinddom Aketon +12% in San d'Oria Shneddick Ring +18% This returns an equipment movement speed bonus of +42%. Verified with speedchecker and targetinfo.

Expected behavior

Movement speed equipment bonuses should not stack. Only the highest bonus should take effect. https://www.bg-wiki.com/ffxi/Movement_Speed

From observation, expected result should be highest single piece equipped, which is 25% (Adoulin zone with the appropriate gear item), or 18% and lower (for all zone)

removed "good first issue" label because given past experiences and average new person skill, I do not feel it is.
