I know that one of the big gripes about Morrowind Comes Alive is being attacked in towns and respawning npc's and creatures.
Also for computer performance reasons you may want to reduce some of the characters in towns. This can help with that too.
The leveled lists in Morrowind work on a "chance none" feature. I have adjusted the percentages from 0% to 25%, 50%, 75%, 90% and 100%.
100% will effectively turn off the list.
This is only a tweak for Morrowind Comes Alive. It will not work without it.
No screens shots because this only affects the random chance of NPC's showing up.
