Starting, Aspiring, Traveler's, & Journeyman's Enchantments don't always personalize item.

Indeed, when you use the scroll to enchant an item with these four, the item will end up linked to the user forever; but it is also posible to find items already with those that aren't personalized... it may be a glitch though. I'm talking about some of the Cumulative Level Missions' Rewards, which can be traded and then used or burned by other characters.

I believe that it isn't personalized until it is actually equipped...I've enchanted a few and it isn't personalized. but after putting it on, it personalizes itself to the character. So it'a possible reason that this occurs?
