FearLess Cheat Engine

I have been trying to enable the ability to stack defensive towers (removing the collision recognition of buildings). I tried passing that part on the tutorial as well and couldn't get it to work there either.

perfect world: I could do it myself
Nice world: someone reply with a script
good world: post a link to a good tutorial video

Thanks community.

P.S. also can't seem to get pointers to work.
