I've got a bit of an update and request for info! We are looking into it, but some more specifics would help.
In a stroke of poorly-timed good luck, the person investigating this played through this event so they could see the problem firsthand, and it progressed perfectly. 🤦♀️Can those of you affected by this specify exactly what is breaking? Is the repair NPC not spawning, the the repair NPC spawn but not fix the cannon, or something else?
