Easter Quest "The Mine Worker" doesn't register special mines

Easter Quest "The Mine Worker" doesn't register special gold mine or industrial gold mine as level 5 gold mine. Feels like a bug to me. This also applies to the subtask requiring to select a gold mine.

Any chances this will be fixed during next few days or do I need to waste some resources on level 5 regular gold mine?

We got this for years already....build one, be done with it, expect no logical update on that from BBs side.

Doubt it. It's like that on Test Server as well.
