yay fixed some shit

============= ============= 1.12 changes ============= ============= 
- FIXED: In level 6, the chemistry set NPC uses a different (and way less stupid) method of moving to the other side of the factory section, which should mean he doesn't just get stuck on walls now. Though, I spent a good long while trying to get this shit to work properly and it SEEMS to be working  fine now, HOPEFULLY it stays that way. x___x

- FIXED: Overmind is highly resistant to magic, yet the game rarely lets you know that because the reaction towards magic weapons (which triggers the "This attack is ineffective!" text) was really low. Now it's almost guaranteed.

- FIXED: Various minor-ish issues in level 6 fixed, such as a teleporter not working, a typo, a script not activating exactly correctly, etc.
