Trying to upgrade PvP bracers from rank 3 to rank 4 have the currency reset is not yet happened (so I do not need a new week victory), today I already upgraded a few other items to this rank.
It did not let me upgrade from rank 2 to rank 3 before but after I drilled socket in it then it allowed to do it and then stuck again from 3 to 4.
Yes I had this issue this morning. Upgraded other slots to 236, but when trying to upgrade my ring past 229 it gave me the error ‘this item cannot be modified’.
It was the case in BfA (u were not able to socket upgraded gear), in this case it something else.
On my monk i can upgrade everything to 4/9 but can not upgrade my fresly bought ring past 2/9 (i have played arena since reset, and can upgrade other items).
If you were to socket the ring rn, you would be able to upgrade it to 4/9, but then again the 5/9 upgrade would be unavailable. It’s defo a bug on socketable items and the bug itself has most likely something to do with the sockets themselves.
Either way, it’s a bug and there’s no workaround, you will have to wait for Blizz to fix it. The fix will most likely come at the same time, as vault loot is getting fixed, so let’s hope for this week.
