A couple more questions from the new guy

[RomulusAugustusCaesar]

1- You have to switch out the EDU if you are playing custom battles. (See the last question on the FAQ.)
2- Unit size is saved in a savefile. If you change unit size and load an old game, it will have the same sizes as when you started the campaign. You have to start a new game to see changes in unit size.

Thanks! So my old games will remain the same size, but won't CTD. GREAT!

Thanks for the answers!
