Curious thing, testing monster compatibility I found that a lich and a necromancer will happiliy co-exist, but toss a vampire into the mix and the fight's on. Examining the factions I found that a vampire is vampire faction and creature faction, vampire faction is -100 for lich faction and necromancer faction and +100 for undead. Necromancer and lich are also +100 for undead, why can't we all just get along?

Odd that vampires are not classed as undead, what I was wondering is when adding leveled creature markers to a dungeon, is there a quick way to test compatibility?

Second question, LL0 (1 2) IC and MQ are easy to figure out, is there a list of what the other headers mean? CG, MS, RF, SK, worst trouble is even stuff like dead bodies aren't listed as "quest object" until I try to place one then I get the warning message. Duplicate a sewer cell or add a door and no warnings, but in game click on the door and get the dialog for some quest script. Testing this stuff ingame gets tedious, there must be some way to run checks in the construction set?
