As the USA, I have seen this happen:
Event:
Started a dockyard in New York (2 available slots)
Arsenal of Democracy started (which would add 3 slots and 3 dockyards). this would still be below 25 slots
After the dockyard completed construction, fulfilling the event, no Completion in the decision panel and no bump in Congressional support, which is at 79H, 284S.
I have seen this happen before, but it was a MIL in Utah.
I suspect that due to multiple foci that added the similar construction to the same state (New York) along with construction a flag was set and not cleared since the Focus dockyards do not fulfill the event, and the constructed dockyards surrounded the event.
