This have happened several times over the last week and it is by far worse today.
When I upgrade a talisman or a character. I select the rune/shard of the appropriate type and move the slider accordingly. Usually all the way to max level or shard or money. I then hit the currency button and the experience bar moves but then stops just short of the max displayed. This happens quite a bit and then I have to go back in and add more money, runes to max the level.
What is even worse is that now I am having rollbacks on my talisman levels and still losing the cash and runes!
I am trying to download a video recorder now to post a video as I have dumped close to 100k plus runes in my 6 Strength Talismans today just trying to keep them at 4* 40 level. Once I level them or play some I come back and either one or two or all of the talismans have been rolled back to 36-38. Currently I have done this three times and each time it rolls back. Now I have one talisman that is level 39/40 and I am waiting to record to show the bug in action.
