Well, thankfully there hasn't been any further casualties from my own shot rebounding, so it looks like that was an isolated incident. Plenty of rubber ball bouncing around though, it certainly looks damned impressive!

Thanks for the points on the explosive vs round shot against buildings :) Though I do find it amusing that explosive shot is specifically mentioned at being especially effective against buildings...

Only other bug that I had last night with artillery was that damned "AI fires canister shot 400 yards" bug.
