Hotfixes
}}
 * - Healing Tank:
 * now no longer increases damage taken by friendly units.
 * can now trigger while the unit which has it equipped is casting its own ability.
 * Fixed some cases where magic-immune units could still be or damaged ( -  stun, Delta Slam - affecting magic-immune and invulnerable units).
 * Fixed a pathfinding issue where a unit would want to move to an adjacent beneficial cell, but the cell was not free, so the unit ended up not doing anything.
