Cranberry won't follow me back to the Hub

### Describe the bug

After clearing out the radio tower, Cranberry says it's time to head back to the Hub, but they won't follow me. They showed on my screen as allied green during the quest, but went back to neutral magenta after starting the "hey we did it" conversation. When I talk to them now, I still get the "Let's set up a combat strategy" dialogue option as they were an ally, but messing around with those settings doesn't seem to do anything.

I happened to be reloading when that conversation started. I finished it with seemingly no problem, but afterwards I got dialogue saying something to the effect of "Cranberry is trying to talk to you, stop reloading? Y/N" and selected "Yes".

### Steps to reproduce

Unsure. Consult my save file. Try doing this quest and see if it happens to you.

### Expected behavior

NPC who says they will follow me back to a place actually follows me to that place.

### Screenshots

Note magenta "neutral" color

### Additional context

_No response_

Start by loading the attached Mindssachusetts-trimmed.tar.gz save and replaying the radio tower quest, including the interrupted reloading conversation. Trace the NPC's alliance state and follow behavior through the "hey we did it" dialogue; done means Cranberry remains allied and follows the player back to the Hub.
