Can't upgrade gathering tools
Bump, I have tried re-equipping and un-equipping. Tried both specialists. Cleared cache/temp.
Since this seems to be an account issue, rather than a game-wide issue, your best option may be to contact Customer Support. Top of Page – Support – Submit a Request.
Good luck. =)
Oh, and you are sure these particular tools aren’t in an invisible bag/box? That may impact their ability to be upgraded.
That may be stupid but did you try to click on the Sickle in the vendor tab, to actually select what you want to buy?
Ohh! Excellent suggestion!
