It's probably an EB problem (or more likely an RTW one), but using Alex means I can't try the savegame. I'm not saying I've got the time for it now though, as is obvious from the very delayed response here.
The disappeared general sounds similar to the army-within-army and AI ghost army issue of RTW. We still have no idea why that happens. Your best bet is to reload an earlier save where it's not happened yet, if it's causing you any trouble. If not, I'd just leave him be, or teleport him off to some remote island to die of old age if that's possible.
The revolt CTD should be possible to work around by the suggestions listed in the frequent issues. If it's in fact the revolt causing it, of course.
