I remember that there were cases when like Vessel of Cathil and Weather Vane with cards like Anti-Magic Shell or Silver Stagg disabling them were also preventing Flux given back from destroyed figure, holding that enchantment.
Few days ago I seen two cases when flux was given back, so I decided to investigate when no flux is given. I tested several cases with this cards and I got flux back in all of them. I'm surprised, so I'm asking if anyone know when exactly salvage wasn't giving flux back with AMS or Stagg.

Also I noticed next behaviour, that looks wrong: when you sacrifice creature enchanted with Vessel of Cathil you still gain flux back. I think that's wrong. There is no clear rule about what happens with enchantments on removed figures, so I'm thinking about changing this to use same reason that was used for figure for all enchantments as well.
I mean if creature was destroyed then all enchantments on it are destroyed as well. If it was sacrificed then all enchantments on it are sacrificed.
