The bug fixed in 2.2.0.5 had been around for a while, and the multiplier value had been adjusted downward to try to get the event to generate the proper number of troops, to compensate for the bug. When the bug was fixed, those multiplier values had to be adjusted upward, as the bug was no longer boosting the values to the desired amount.That surprises me (haven't checked in game as of now), as they added the "- Fixed bug where all event spawned troops that scaled on a target was MUCH larger than supposed to." in 2.2.0.5,
but added "- The Rise of the Shia revolt is now much bigger." in 2.2.0.8.
Hmm...
