Fix potential runtimes with Cult mobs
Created by: dylanstrategie
- Ensure that escape_list has actual contents to pick from before picking through it
- Ensure that we don't try to grab that list if it would be useless (discared if the distance to the "shuttletarget" is less than 2)
- Don't regenerate the shuttletarget constantly, causing us to get stuck (most likely an oversight)
