I have a question in about this. It is a bit late on a Friday, so hoping to hear back. Biggest issue is that once a mission goes into the wild it may be unable to be altered after players begin to complete it.
This is most likely an oversight if "Assisted in Capture" ribbons are not counting as Solo Caps can be a high ask, certainly.
Players have wanted to finish the Transformers Collection for quite some time. Premium Containers do not offer Collection pieces so there is no benefit to making a hard mission in the middle as that runs counter to our hopes. We have a LOT of containers to do our best to help players finish out the Collection even if they are only just starting it with this part of the Collab.
