Demonologist Sustainst Don't End On Rest

[San0ix]

I don't exactly know why, but it appears that the Vim draining sustains don't deactivate themselves on rest. This also seemed to only happen once I had Osmosis Shield and Rain of Fire.
On another note, could you make Blood Shield also work like that? It's kind of weird to have a Vim draining sustain that doesn't end itself when the other ones do
