Upgrade Planner not working on entity despite next_upgrade being set

[keeper317]

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.

Are all the requirements met mentioned in https://lua-api.factorio.com/latest/pro ... xt_upgrade?

it's because your loaders are hidden I think

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