Enchants dissapearing on heirlooms

I dont know if this is the correct thread to ask this question, move it to the proper one if so.

Anyways, i just faction changed to the horde 2 days ago on Icecrown, and wanted to start leveling a priest. I had my heirloom chest enchanted with 100+ health and my staff with 30+ spellpower. I mailed it over to said character with some gold and bags, and to my surprise after i hearthstoned from brill to deathknell, my enchants had dissapeared? So when i got back to brill, i mailed it over to my main again to see if they returned, but no. So i re-enchanted it, sent it back to my priest, and after i had to relogg, they were gone AGAIN!

So, im guessing this i a bug, right? OR, it might be intentionall, i dont know.

Anyways i hope to get an answer quick as this just ruined my day tbh.

I just experienced something similar. I enchanted crusader on two weapons and 100 HP on an armor. All items are heirlooms. After mailing them over to my alt all enchants were working properly, untill I switched around my weapons and logged out. All three enchants are now gone.

Would like an answer to this as well!

similar issue from retail player... here but there's no actual "this is why it happens" "this is how to fix it"... my suggestion is to get some enchanting vellum and scroll the enchant to then use it on your alt... see if that works

It`s related to the suffix items losing their stats and the 'no charges left' issue.
