Maybe there isn't a limit of three random events?

[Action]

I always hear people say there is a limit of three random events, per faction, per turn. And anything higher is caused by provinces changing hands or by enemy spells that pretend to be random events.

I am looking at a turn with four random events, all beneficial. Presumably none of these are enemy spells that pretend to be random events.

Slave labor improves resource production
Silver Mine found, 40 more gp per turn permantly
Silver Mine found, 40 more gp per turn permantly
Priest frightens people, increasing faith and generating 300 gp of donations.

None of the provinces that got events changed hands this turn.

Luck 3, Turmoil 3 scales (and more gold than I know what to do with hehe).
