I've been bughunting the last couple of days and I've found some dodgy maths bugs.
I got the morale bug, morale was on 99 although my real morale should have been much lower.
Prisoners bug: I was able to take as many prisoners as I liked with only 1 point in prisoner management, occasional I would get a message saying 'there are too many prisoners in your party Xnumber of [insert troop names] leave your party, however even then it didn't take it all the way back to 5, like I had 15, got the message, some prisoners left but I still had 9.
Party size bug: For some reason the maths in the reports wasn't adding up again, I should have had about 40 troops but I could have 99. I tried it out and 99 was indeed the maximum, no messages about party size or anything.
I am using battlesize changer, apart from that no changes to module.
