Found a new bug - don't know if it's specific to my campaign or with RTW / the mod in general. Playing as Araby, if the Brettonians besiege Magritta from the North-East then if i click to sally out against them then it goes to the egg timer and it either stops turning or else keeps turning but doesn't go to the battle. Tried assassinating the character leading the army in case he was the problem. No difference. If i wait till the assault comes it plays fine. If the Brettonians besiege from the North-West it works fine too.
