Yes, you are right. I reverted from beta e1.4.0 to stable e.1.3.0 (now 1.3.1.), and with no mods at all it works, but with any small mods added like ModLIb or BannerlodTweaks...it crashes soon in the game play. I hope it is something fixable, either by Tele, either my modders community. The game without some basic mods, it is very hard to play, in a time-consuming matter....it takes an exasperated amount of time to make small progress. I must say that I am currently using a retail version of MB2
