Sylvari starter focus causing dye bug?
I actually had this same issue, but it wasn’t on a Sylvari, nor on a beginner character.
I have a level 80 female human Elementalist on Henge of Denravi server that I bought karma gear for, that had this same crash issue. Every time I would try to a specific part of the new boots the basic dye color “Autumn”, the color would revert to “Dye Remover” (even though in preview and before I closed the dye tab it appeared as if the color had stayed), and unequiping the item always resulted in my game crashing. The funny part is, ANY other color aside from “Autumn” would dye normally, and unequiping the boots with those colors didn’t cause my game to crash. I also had no problems with the boots I’d had previously (which I’d just transmuted to make said “Crash Boots”) nor did I have issues with any of the other karma gear pieces that I similarly transmuted at the same time as the boots.
I didn’t try recreating my character (for obvious reasons), nor took the same measures you did in trying to fix it, mostly because it didn’t occur to me to do so at the time. However, I did file an in game bug report and ticket about it, and the issue eventually resolved itself (I never did find out how), but my Crash Boots sound a lot like your noobie crash armor. I wonder, did you use the same dye color I did perhaps? Or maybe there is some other link between our issues? The only thing that changed since my boots made me crash, aside from time passing, was me getting her a new staff and some Ascended rings.
I tried several dye colors, although it was one of the default green ones (Jalapeno?) I initially intended to use. It didn’t seem to be related to the specific dye color.
Another possibility is that there was some “memory” somewhere (either stored locally or on the server) of my initial version of my character that did not get removed properly when I deleted the character and re-created it. And then somehow the difference between the saved information about having a shield vs now having a focus caused the issue? If such inconsistencies could occur, then perhaps they could occur at any level due to some hiccup (disconnect, glitch, etc.) which results in the inconsistent state manifesting in the form of dyeing issues. I dunno.
