It can't be the player's responsibility if by simple accidentally clicking on a mound you instantly unlearn two skills - that's crazy. A simple "Confirm / Cancel" prompt should be enough to avoid that.
Yeah that happened a while back and I reported this one. IMO this is of high importance how this works. Learned spells in which you go out of compliance with (lack of a better word) should still be learned, not useable and when you get the pre-req again the spell can be activated. Not repurchased. To me this is a biggy.
