I found a work around. For the champions that you are trying to use as food, remove all artifacts first. Then, when you add them to be ‘eaten’, it will give you the warning about them being a fusion champ but will then add them. I imagine t has to do with the fact that it is warning you about the fusion thing, but also is needing to warn you about there being artifacts on the champ as well and something messes up.

WTR (way to reproduce an issue):

Step 1: Go to Tavern;

Step 2: select Sacred a hero you want to upgrade 6 stars;

Step 3: Select a heroe you want to sacrifice and who has the ability to be fuse;

Description:

A reminder pop up, asking if you are sure you want to sacrifice a hero who can be fuse. When you click 'YES'... Nothing happened.

That was the case with 'Slitherbrute' and 'Spirithost'. 

Don't know if there is the same issue for the 4 stars and less.

Same problem here can't sacrifice champion that can be used to Fuse another champ.

Even if I click "Sacrifice" it's doing nothing.

I tested again.
