[1.74] Mecharachnid changing stat requirements

[Caliginosus]

I gave my Mecharachnid Tarrasca to attach a Tinker to it. It was able to equip it as it uses Dex for stat requirements. After taking it off it changed to 52 Dex requirements permanently. Now my Worm That Walks wears it, still showing 52 Dex requirement. I'm using a tooltip addon, but I actually had to get the 52 Dex to wear it.

I'm playing on an Adventurer an with some addons, so I might have to do some more testing if it's not replicable for others.
Cheers!
