Same problem here. After a week of waiting, my rare gun/assassin soul counter was showing 4h last night. so I woke up this morning with hope that I might finally get some 5* character,which would help me over that brick wall I have hit like two weeks ago, of having a handful of maxed 4* characters and not being able to beat LotL8 or any further campaign levels. so...long story short (i bet 90% of the player base is struggling with the same thing) i opened the game in the morning and the rare gun/assasin soul counter is locked and shows 6 days again?!!! at least I was able to buy a rare warrior soul again (got some useless 3* crap again...as I always do) which was invisibly locked for the last few days. so no chance to further evolve anything(since LotL doesn't drop 3* evos for me)or a chance to buy a stronger character and the waiting continues....
