Thanks, fixed for the next patch!
I am still getting this problem on the 0.6.16 patch.
Which god are you trying to upgrade, which upgrade are you trying to use, and how many emblems from that upgrade do you have?
I am trying to upgrade Regalis with the Surathli upgrade. I have 203 Surathli emblems and 100% Surathli mana.
Think I’ve found the issue - thanks for the information!
