Warlock invocation acting weird

[Necro]

XWARREN,

My Dread Necromancer/Warlock/Eldritch Thuerge casts summon undead 1 and gets a skeleton.  I then do the warlock summon swarm - bat and the bats attack my skeleton and the skeleton takes wounding damage.  The description says the swarm should only attach enemies.  Also, why would undead take wounding damage anyway?

[xwarren]

Swarm damage script uses SPELL_TARGET_STANDARDHOSTILE filter to select targets. This means that it will work just like fireball spell - in low game difficulty mode it will target only hostile creatures and on hard-core mode it will target all creatures.

Any suggestions on how this should be changed (how should swarm damage work in NWN)?

XWARREN,

Doesn't the invocation descrition say it should work only on enemies?


Also, why do undead take wounding damage?  They don't bleed.
