Description: A mercury resource has no icon on map before Artisans Quarter is placed on top of it

Attachments #1: Screenshots

As I hoover my mouse above the tile where the resource is (the one with 2 money and 1 industry output that is below lead resource) the description shows me that there is "Mercury Deposit" there but there is no icon above the field:

When I want to place Artisans Quarter somewhere the mercury tile is highlighted, but still no icon:

The icon shows up only after Artisans Quarter is build:



Steps to Reproduce: I don't know, it's just how it looked like for me. It stays like that after reloading the game from other saves, I tried changing language and it didn't help.

Expected Behavior: There should be mercury resource icon before Artisans Quarter is build on top of it
