If you meant that you're getting these items from the gold collection everyday, but they vanish, it could be because your inventory is full, and the game only stores them temporarily. You'll need to clear your inventory (event junk usually clogs it).
If you meant that you're gathering them, but they're of no use for your tower/magic upgrades, then there's nothing to be done. The game's built that way.
I'm collecting, but they are of no use to your tower / magical upgrades, the earth essence it is necessary to synthesize to achieve pure earch essence, which will be used to upgrade the magic ward, or for sale, could not go away from my inventory.
as well as several stones disappeared from my inventory, I noticed the disappearance of gold, now gone exactly 12.574, what's going on, if not reimbursed and disappear again not play anymore.
