So- you load your game, try to save and have CTD immediatelly? Or you try to save after location chamge? If the last- try to make masterupdate.
Yes, you must recreate merged patch, without it mod will work incorrectly. Don't forget to make upgrade from old FWE/MMM in save place and in accordance with MMM instructions, it can be source of your problems too
It was immediately.
But anyway, I downloaded the latest versions of MMM, WMK and the respective FOIP module, ran MasterUpdate, created a new merged patch, and voila: all is fine when it ends fine.
I was heavily afraid of damaging my saved game beyond repair (since I don't have the the older mod files anymore -- the zip files), but now I'm glad I took the risk: especially because of this new in-game FWE menu, from which I can easily fine-tune the game according to my own play style: two thumbs up!!
Thanks for your help, and for reminding me of the MMM instructions concerning the savegame (wait for several days in a no-respawn area in order to reset everything, etc.). Cheers! :foodndrink:
