Disappearing chargers

Update: now they have removed 97 gems, which I had purchased! This is THEFT and fraud. I assume they did this to force me to buy more during their current sale. Do not bother with this manipulative and fraudulent game which I had once enjoyed.

You keep removing chargers from completed, but not submitted collections. I have had all the chargers for the Fan collection twice, but while waiting for it to appear in the Quest queue some of the chargers have disappeared. This has also happened with Meturet andVigor collections where the number of chargers is reduced for no apparent reason. This unfairness causes losing interest in the game from a regular customer. A dangerous business model.
