1- If You attack and deal damage to AI and cast then Ivory Charm to prevent damage then if you select tap you can't tap a creature when asked but ONLY damage card on opponent is found legal and prevents that damage.Like stassy says.
1A- The Tap option is only selectable if player has been dealt damage.
BUT:
2-if I try to use the regeneration option when my creature has been dealt damage I get this error:

I click ok for the error and then I am asked to "select damage card" but both damage card on my creature and me are found "illegal where" and the only option that is allowed is to target me (the player banner has emerged)

EDIT Also has this really annoying behaviour to ask at every trigger step.etc for regeneration effects.

Problem isn't the menu; it's that the prevent-damage target's info overwrites the tap-creature target, and never gets initialized itself. Fixed 1d652b1.
