FMH - nights of bugfixing

I've been busy.
A rather decent chap in Australia (how cool is that, someone literally around the world is using my app!) sent me a lengthy email detailing a tonne of bugs with O&G.
I fixed the vast majority of them tonight.
A bunch of facepalm type ones, for some reason I had all cavalry as down as 20mm wide. Seems like they're all 25mm wide, there's no such thing as 20mm cav!

There was an almighty bug in the code which determined how many models could attack units of smaller base sizes, with fewer models. This is now fixed, it took a good 5 hours of work to fix this bloody thing. When I fixed trolls attack count, it broke cavalry attack counts. When I fixed those, it broke larger monster attack counts. Thank fark I started implementing unit tests, else I wouldn't have known I'd broken the attack calculator for other units.

That's me, and the demon is the bugs. RAWR.

CHANGE LOG:

- Regeneration
