Warcraft 1 Remastered: AI does not mine gold

Hello there,

I bought Warcraft 1 Remastered and am playing the Humans campaign (I haven’t completed it yet, still in mission 7 or 8). However, I notice that the enemy does not harvest gold. Additionally, it continuously sends peons to my camp to harvest lumber there, while it is also available in their own camp. It happens in multiple missions.

Is this issue known and will it be fixed?
