Upgraded Immortal Kings Set changes level requirements after being equipped

I have an upgraded IK set with the gloves and helm already equipped. If I then try to equip the boots it changes the level requirement of the gloves from 64 to 71 making both items unequippable. Even if I then remove the boots again the gloves can not be worn and won’t be equippable again until next login (though tooltip suggests they are meant to be equippable again).

This bug report facility does not allow links so not sure how I submit a video of it in action.

a Necromancer has entered the chat…

(16:25) He says the Gloves have req lvl 64 requirement in the video, which it did in the cube and inventory, but after he equipped it, it became req lvl 71.

(17:20) He also says Belt has req lvl 67, which it did in cube and inventory, but after equipped, it becomes req lvl 74.

(17:43) He still says out loud, that the Boots when upgraded to elite are req lvl 65, moves that one straight to his character, and it becomes req lvl 72.

The helm wasn’t recorded, since he was originally unaware that the helm was actually normal instead of exceptional. He later comments that he figured that out, and wanted to include what he found for the Helm. While in the comments he states (abbreviated version):

Avenger Guard, lvl 47 Requirement

Slayer Guard, lvl 52 Requirement

Guardian Crown, lvl 77 Requirement

Not sure if the 77 is before or after equipped, but I’m guessing ‘after’ since its in the 70’s.

Edit:
Ogre Gauntlets base lvl req is 64
Colossus Girdle base lvl req is 67
Myrmidon Greaves base lvl req is 65
Guardian Crown base lvl req is 65, so if that is bugged too, it would show 65 until equipped.

Which leads me to conclude, the higher lvl requirements are correct, its just bugged until equipped to display the proper lvl requirements.

I fully upgraded Sigons gloves and boots. Same thing.
Gloves level 64, when equipped it says level 76
Boots level 65, when equipped it says level 77
