Inappropriate To Marry FIX  

Having any other relationships can cause this to happen as well. This may or may not remove the greyed out because of another relationship Thank you fellow whatever0623.
However, In my autonomous Proposal mod, you will have the option to have a polygamous relationships.

It has been brought to my attention that MCCC has this option as well. This mod does not conflict with MCCC.

So what did I do to fix this? I removed the codes that told the game to check job situation. With this gone, a job situation of any kind shouldn't interfer with whom you want to marry. However, for some reason I am unable to get it to work fo the wedding arch, you can still elope just fine.
