Unable to evolve weapon

[Rusa]

Just got back after not playing since... last year? or so? and I was trying to evolve my weapon. I have the mats, I have just enough gold but nothing happens. It say "evolving weapon..." then goes back to a normal screen. That's it. I'm not sure what's changed or if maybe it's on my side? I'm very confused.

What weapon are you trying to evolve? recently all weapon paths older than Riftwalk / Dawnforge cannot be evolved anymore.
