I've never sent an army along with a Crusade - I usually take units and toss them into the Crusade stack.

If the non-Crusade army stack was led by a Gen with more stars than the Crusade Gen, or if the Crusade stack was smaller, maybe the comp gave the province to the nons.

I know that when I've taken a province with a regular army while I had a Crusade enroute, that the Crusade disbanded and I got a message.

Maybe I'll have to test this . . . .
