Hi, like to say, great mod with fab unit balances!
Now to the meat of the post.

Seems about 50 turns, the game gets to a point where it always seems to crash. Im english, it goes thru the AI for french and HRE, and then goes half way thru the spanish turn before it crashes at the EXACT same spot. This has happened in 2 campaigns at around 40-50 turns in and I see a couple of others with similar problems. Im only using this mod so unless this is due to the stock game (would think to hear more complaints about in the general forum), then there seems something slightly up.
Using a merchant i have in the area, i scour the spanish areas looking for abnomilies over multiple crash-reset-crash-reset etc cycles and i see it "could" be something to do with a spanish cardinal and a byzantine diplomat. No idea what it could be but if this becomes a problem for more people, it might be a good idea to look into agent AI (cardinal thinking he wants to interact with the diplo???... still could be a red-herring tho).
Systemlog file reports an Unspecified error, doubt thats much help.
Anyway, this incrediabily annoying problem has put a hold on my Nation Wrecking past time untill 1.2 patch or an update for LTC... shame really, never got to use longbowmen :S

Cheers all, and especially lusted for an excellent mod troubled by an annoying crash.

P.S. ive got the save-game so if any1 wants to have a check, then just let me know.
