I wouldn't necessarily call this a bug or an exploit. It took me quite a long time in my current campaign and a lot of cash and goodies to get the Pope to be my ally. Thus with all that effort put into it, he should behave like any other ally, which he has so far in my campaign.

- Ballistae refuse to shoot at enemies at a slope below them even though there is a clear shot possible according to my screen.
I think this may be intended, BUT am not sure. The bolts travel at a certain speed and (IIRC) the equipment itself behaves like archers or towers, where there's a min and max angle they can shoot at. If they're unable to shoot below 0 degrees, with 0 being horizontal front, then that would account for the situation you ran into.

- Negative unit display?? (My venetian allies had reinforcements which didn't show on the battlemap. Maybe that is the cause?)
Spontaneous reproduction!

Also, good work on the bug hunting so far.
