This is a minor bug I encountered when putting gear that had been dyed in my bank and then using it on another character:
I made a character, but at level 5 I decided I wanted to change her look. So I removed her gear, which I had dyed “pastel pink” (unlocked color), put it in the bank, and deleted her.
I then remade her, took my new character to the bank to get her gear, put it on . . . and it was still pastel pink! My new character does NOT have any dye unlocks, and when you go to the dye menu, it does not show pastel pink as being unlocked. But, the gear she is wearing is clearly shown as being dyed pastel pink.
Again, this isn’t a huge deal since it doesn’t actually unlock the color. And I’ll be unlocking that color again anyway . . . but this probably isn’t working as intended, so I thought I’d mention it.
