hehe,I just need to remind you that you're playing an unavailable development build.
1) Patriotism should only give +1 morale, I'll update the tooltip.
2) Heroes with engineering get first aid tents, just added that. I'm not sure if they should also get ballista? It's incredibly OP the first couple of weeks. I'll consider it, I guess?
3) I love the glitched effect whenever you load a save from an earlier version. Save files are only compatible for the version they were made in, and that's fine by me, since I'm planning to y'know, actually release a v1 soon, so that won't continue being a problem.
4) For the Identity update, which, mind you, you've got an unavailable development build of, each faction gets a pair of mutually exclusive creatures. So, yeah, just six different units for hire in each castle. This is on purpose. Like a very, very lite version of the HoMM 4 system. Look forward to when v08 is actually released. It'll all make sense... (hopefully)
