Doing my first Roman Restoration-game tonight I just had an independence faction declare war upon me. The faction, being led by the Doux of Damietta, backed primarily by the Despots of Armenia and Syra, didn't seem to be too much of an issue, and when the war started I marched my 20 000 man strong retinue from Alexandria into Damietta. Immediately when I crossed the border I got the 'Rebels get support from brigands'-event and suddenly 150 000 men popped up in the duchy -> I got my butt kicked and did a rare rage-quit. Anyway, is this working as intended or was it just ridiculously bad luck on my part? I've encountered the event before when Jerusalem and Syria rebelled together, and then Jerusalem got some 25000 extra men, which seemed descent enough.
