when my caster is right next to an enemy, I mouse over the enemy and it says "need to target an enemy unit". I don't think I've ever gotten it to work in LH so far.
Just did it and it worked for me. It can be difficult in certain tactical maps to select the proper tile with the mouse. Have you tried rotating the map and/or zooming in with the mouse wheel?
Don't try it diagonally. It now does a area 3 tiles wide, so you need to select a tile at one of the cardinal directions.
yeah it worked again later. must have been the diagonal.
