Your followup post would have been better placed as a reply or edit, rather than a separate topic;
Addition to my previous post (freeze in act 4 beginninng...) If i cllick on f1 f2 or f5 I can now see my characters (I saw nothing but background before.) The map key works (A) as do some others, but I cannot move my characters, though they deem to a'breathe"; that is, be alive and not frozen.I read a previous posted answer about deleting the Acts Dynamic forlder files. Is this a work-around that will help me?
Which mutant (location) is it that triggers the problem? Do you know which cut scene is suppose to start then? Did you try different ways of killing the mutant (weapon vs spell), or having a different character do so?
A couple people had a similar problem with the traveling merchant in act 3, who had his goods stolen. If they killed the mutants first, killing the air elemental would cause a hanging cut scene (or maybe that was the other way around), but if they killed them in the opposite order it would work properly.
Beyond Divinity mapsDeleting the files in the dynamic folders may help (couldn't hurt, anyway), but this doesn't really sound like that is the problem. The dynamic folders are;
'
..\Beyond Divinity\Acts\Act1\Dynamic', '
..\Beyond Divinity\Acts\Act2\Dynamic', etc.
These folders are used as a cache for the game. Files are created / copied there from the save game folder when you load, and written / copied to those folders when you save a game. The files will be re-created as required the next time you start Beyond Divinity. If there was a corrupt file in those folders, deleting the files should fix the problem.
