Hey there guys,
Apologies for our delay in getting back to you here!
This was something that was raised to the game team previously and was confirmed to be working as intended.
"The long production times and large output storages of the new buildings make the range very long comparatively, however if the output storage runs full then it would be a bug.
Since the production did not stop during delivery, the next producer has the higher priority, as long as the production is not hindered by this, the state is as designed."
This has already been noted as feedback to the team, to which I'll happily add your comments on.
If there's anything more we can help with or you'd like to share, please let us know!
