Does a Harvester on a Field make a difference

RAYMONDRONALD

I have had mixed answers on this so if EE could clear this point I would be grateful

TIB field no Harvester on it I place a Refinery next to it, would I get a higher gain for the Refinery if the Tib had A harvester on it

Same with crystal field and a Power plant

Afaik the Harvester does not influence the Refinery or Power Plant in any way.
Silos boost production of Harvesters, Akkumulators boost Power Plants and Power Plants boost Refineries.
Crystal Fields also Boost Power Plants and Tiberium Fields boost Refineries.

Whether a Harvester is on a Field or not should not matter for the Refineries adjacent, there is no negative interplay.

Thanks can save spots for refinery's instead of Harvesters
