making hero spell from unit abilitys leaves me with no icon

hi all, im trying to making a hero spell from a unit abilitys but when i do this leaves me with no icon jsut a green square when u choose your ability, but its ok in game?? any help cheers

My guess is that your spell doesn't have an "art - icon - research" defined, so the game shows the green square of death in it's place, as it always does when it's missing an icon.

By the way, this thread should be in general development forum, not the triggering forum.

ill try this and see whats happens, thx for replying
