Since the Install of Patch 1.5.2 the game crashes without an error message always when raiding a monestery or encampment durring a fight sequence. (So far in England or Ireland) So, as a worksround, I go in alone and kill everyone before starting the raid, then I use the horn to call my shipmates to help me open the large chests. If raiding a monestery with a church that needs two to open, then I stop there because, if I then get help to open the church, to fight the last few and rob the last few chests, it crashes as well. so basically no shipmate fighting in raids. I hope you get this fixed soon. This is a really bad bug because raiding is a main part of the game.
just like many other players I have already tried all normal actions (re-installing) etc.
thanks!
