To echo the question above, has anyone actually amended the necessary files to get things working? I'm still on 1.10, and not updating to 1.11 until they sort out the bugs... and a little confused by the coversation between happycats 517 and DragonScythe above.
Well, that's the thing, unless I'm missing something, my files SHOULD be set up so ANY religion is alright with marrying ANY OTHER religion. However, when I test this, I still always get a no with "----- must not marry infidel".
Looking at the religious files, it seems like all it should take is adding:
"intermarry = <religion>"
to the entry of a religion if you want it to intermarry with another religion. I've done that for each religion, adding an intermarry option with every other religion in the game, but it doesn't seem to alleviate the "must not marry infidel" problem. I think I'll do some more basic testing to see if maybe I just screwed up somewhere.
