Egg delivery quest, Hot Springs

[nfr 0]

Due to a significant delay (up to 5-6 seconds)when handing over the deliveries to the dwarfs, if a player clicks twice on a dwarf it will take 2 deliveries and return 2 coins but the quest will get stuck. In my case, Kuber took to coins and I have to restart the quest now because I do not have enough deliveries to complete the circle. Here is a screenshot.

Good afternoon, @nfr. This quest works correctly. The error occurs when there is a huge load on the server.
