A lot of the functions were made to create "flavors" and specific behaviors for aliens, but it is not defined enough to handle many scenarios that might occur. This issue becomes exacerbated with player abuse. So most of these mods just disable those functions, or changes some numbers. 

All of these are single hex edits and are all save game compatible. Install with patchergui/longwarmod manager

1. Suppressions fixes - suppressionignore.txt is what stops the aliens from priority targeting the suppressor

2. Functions that call suppression are scattered so there are a lot of files. It disables references to suppression. Ongoing tests.

3. Cyberdisc and drone "reasonable attack range" (they won't shoot past a certain range) - back to visual range. Easily abused

4. Mechtoids will stop when they see one person or more (instead of 2 or more) with hitchance of 25 or up, Hard to test.
