"There are some mining designations outside of mine tower areas" - where?

It's a big island... please let me click the message to see where, even if it just jumps to one of them.

Press M or Z and looking for the Yellow squares outside of your mining towers set area.

Sample:

I would like to second this bug report. I spent half the game (30+ hours) with this message spamming me because there was, somewhere, a mining designation outside of a mine tower area, but I couldn't find it.

This was fixed as part of Update 3!
