Upgrade Planner not working on entity despite next_upgrade being set

I have a deepcopy of the 1x1 loader, which typically does not support the planners. I have gotten the BP and Destruction planners to work, but despite setting the next_upgrade on the loader, it does not work with the Upgrade planner.

it's because your loaders are hidden I think

Thank you, it was an issue of the items being hidden.
