With the update all mounts including Kelrok, Djinn Nightmare capped at 39% (I though this mount was supposed to stay faster). Tradeskill AA mount speed buff and Vah Shir Mount infusion do not provide any speed buffs. I do not have any purchased items from LoN that provide mount speed buffs but I see people in chat saying that they do not work now.
I confirm, no item was taken into account apart from the speed of the mount itself. i.e. 39%. journeyman's boots of adventure, crafting AA speed buff are not taken into account
Same with the basic mount speed and the Journeyman's boots of adventure. My run speed is equal to my basic mount speed of 39% for Frostshadow Tyranodon. I tried cancelling both and starting with one then the other and speed will not update past basic 39%.
just to add, this could be a text bug or something borked introduced back into the game. Have seen some discord screenshot 'snips' posted -yesterday- of people with 120/125 speed.
