i use the hallway cheat thing as well, but i only use it for money and energy, i don't mess with there stats, i just do the repeat steps to build there stats up and yeah it takes some time to get them up there, but i don't have any problems with the triggers.
I'm also use v0.26 beta 2, which has no bugs it seems like and i'm on my 2nd playthrough still with no problems. I was using 26 final but then i switched over, and yes, you can load your save up from 26 final in 26 beta2 without moving saves around.
This is where you can find 26 beta 2
You must be registered to see the links
I put the zip file into the folder where final is at, unpacked it, so there is a folder for final and a folder for beta2, loaded up beta2 than loaded my save.
