Trying to drink a Greater Cure potion not on the correct path for this mastery ability

TimSt

I have gotten the "You are not on the correct path for using this mastery ability" message twice when trying to drink a greater cure potion.  I had just been poisoned by a dread spider and my greater cure spell had been interrupted by the poison so I went for my greater cure potion. But got the message both times I tried to drink the potion.

As far as I’m aware, everyone without the poisoning mastery active is receiving this message every time poison damage ticks. And this issue has already been reported.
