Okay now I am a bit concern and the only reason I know is I track all my troops and down to 2 dozen this last week that I am soul farming for to get them as far as they can go (everyone else is)
I have a very intense spreadsheet.
I keep having a troop each day that I level up - loose their level (meaning those souls are gone and they are back at the level they were the day before I leveled them up)
At first I just thought it was bad booking on my part. Now I know something is up with Unity.
Yesterday I went through my troops ALL of them update the spreadsheet. And updated 2 of the last 5 legendary troops to get them to 19th level.
Today went to finish the last 3 of the Legendary troops and found Frost Lizard is back at 10th level and I know he was at 19th yesterday.
Today I have only 7 mythics left to get to 20th level. I will monitor this, but it is bugging me that I’m seeing this. 4.5k worth of souls and real no way to prove this is happening.
UPDATE 7/22 - I found a pattern. If I do the leveling on the mobile, the use the PC later - that troop doesn’t stay leveled.
I am going to do some more testing next time I get someone who can be leveled up to see if that is the case, but it happened with Corrupted Urska .
