Upgrade complete. 85 Gems have correctly been deducted, but Glory still shows 684.
What you were expecting to happen, and what actually happened:
I upgraded all Sentinels to V, but the Glory was not deducted from the total. I thought I had 600 left, and went to spend it on the Glory troop. The game kicked me back to loading screen because I had insufficient funds.
How often does this happen? When did it begin happening?
It’s been at least a year since I noticed it, but I’m lazy, and hadn’t ever reported it.
Steps to make it happen again
Go to GW Sentinels and spend Glory (Gems optional). Gems will get subtracted. Glory will not. (Other Sentinels deduct Gold, Gems, and Souls as expected).
