The Yellow Lotus potion has issues, it removes some learned Feats that should not be removed when used.
More importantly, I think, is that it breaks Sorcery Progression when used.
As folks are more likely to be resetting their Attributes more often since the complete Attribute rework, this is leading some folks into a game breaking situation, with no known solution.
I think that until the Yellow Lotus Potion can be fixed to work correctly, that it should be removed from the game to prevent Players from breaking their game.
There has to be a way to reverse selections because people change their minds or mistakes are made. Removing these is not helpful. Those that need to should know the risks involved in doing so but the option still needs to be there.
The reports I have been reading indicate that after using the potion the Tome disappears and cannot be picked up again in the cave.
Perhaps this is related to something else, but my interpretation was that it was Potion related.
