I've looked into the Bandit Expansion raids with FCS and it seems like the "wrath" raids (like the one that berserkers send if you took Ghost prisoner, or other bandit faction with their leaders) are supposed to "die down" after like 2-4 victories.

As I see it in FCS, the "wrath" cannot be repeated naturally (it has 9999 in the "days to possible repeat" parameter), but, on raid defeat, it triggers the "[triggered]" variant of the same raid with 100% probability (that variant can only be triggered, it doesn not occur normally).

And the "[triggered]" variant can then re-trigger itself on raid defeat too, but only with 40-60% probability depending on faction, so if you survive 2-4 attacks they "should" die down.

Does it work like this?
