Fiance Died, Can't Get Engaged to New Boyfriend.

It's a bug.

Try this: http://sims4.crinrict.com/en/2014/09/widowed-sims-cant-remarry/

I tried it and it said "sim not found"...ugh!

Does the dead sim still show in the relationship panel ?

They do show up but they are faded out because they are deceased.

Then it should work-

Did you double check if you spelled the name right ?

Yeah I did. I guess I'll keep trying.

DId you get that message for both Sims or only the dead one ?

I got the message for both sims. I've tried the cheat multiple times and now I got rid of the urn. With the new patch you can bring sims back but you need the urn or tombstone, I have neither. Will they fix the problem eventually so that when a sim dies the relationship dies also?

This just seems like an issue other people will have. I've seen other comments similar to this problem.

The relationship is supposed to be removed. So the Sim now no longer shows in your relationship panel ?
