Okay, I can confirm the issue is with a delay. I made a new settings list, using 4 Slots to gather ore, using miners (I have 16). 'Cos I had surplus miners, the bot never had a problem with having an asset, so it didn't need to wait for the Gateway to release the asset being used, deactivating the slot. I would suggest adding a delay timer to either the Gather function or the Task function, so we can alleviate this "bug" and give the Gateway time to release the assets being used, for people with only one Professional/Asset.
