Computer player - Resource gathering problem

[Pharos]

Currently working on a map where two players are teamed up with two computer players (no AI.) I currently have it triggered so the workers gather gold and lumber at the start of the game. Unfortunately, if for any reason the lumber gatherers stop harvesting, or can't reach a specific tree due to being blocked off, they seem to go straight for the goldmine despite there already being 5 workers.

If I disable the trigger to gather resources, all workers flock to a single gold mine regardless. Is there a way to stop this?

You could make a new AI that only has harvest priorities.
