Normally Cleo drops stop after the 6th.  This mod makes the Cleo drops continue indefinitely (for Story and Breakdown). 
After the first Cleo drop on a level, the following drops will occur ever hour.  If your save already has a completed Cleo mission you'll have to start a new game for the mod to take effect.

See the readme file for details on how I modded it in case you want to do the changes yourself.

There is also a fix to the "ran away" trait bug. (I didn't put that fix in a different mod because they both use missions.xml.)  The "ran away" bug causes the afflicted to get stuck in that mood unless they become sick, hurt, or have a chancy next day event (thanks to a post by QMJS for that information).  The mod won't fix someone who already has the "ran away" trait; the fix is for future run aways.
