This is in my game against AI.
The following is the sequence of event leading up to the bug:

1) Energy is cast on to my dragon.
2) (The AI do something I can't remember)
3) The dragon attack dwarf axe nearby
4) Another dwarf warrior is cast in the dragon's reach
5) I can't move the dragon to attack that dwarf warrior

best luck with debugging

Your dragon is grounded after first attack, so it can't fly over enemy figures.

While that position is consistent with the creature being able to be attacked by ground creatures, aloft says *nothing* about this. It says only that you can be attacked after you melee a ground creature. To me, the logical consistency of "groundedness" is not worth keeping if it means implementing behavior that is not documented in the description of aloft.

So after the first attack it behaves like "hover", huh?
it is making some senses but as Kash said it is not documented.
