You DO have a short period of invulnerability, it's the time where the main character is blinking. If you want enemies to wait longer before they attack, simply increase the "Enemy Behavior" option "AI Delay Time".
@The main character: I was doing those updates during the week of my exams. It's rather natural that I messed up. (^_^') But yeah, to maintain such a huge script isn't easy.
@Aqua: Damn... Alright, give me a few days, I'll put up v1.98 and fix Tons. And yes I meant Part 3 of Tons.
@Sin86: Blizz-ABS won't work with SDK 2.x. Going back should be possible, but it depends on which SDK dependant scripts you are using. I'm not sure if Blizz-ABS will fully work with SDK 1.x, but this is much more likely than with SDK 2.x.
Now, the problems that happen with SDK 2.x are, first off, the automatic disposal. SDK disposes windows and stuff automatically when exiting a scene, so the attempt to dispose stuff in Blizz-ABS's mods of the scenes will cause a crash. Other problems were edits in the some scripts and the splitting of methods. I just remember that I once tried to see what the problems were so I could fix them, but after 15 minutes of constanly new errors (I only overrode the problems, I didn't fix them), I realized that making those two compatible would be a hell of a job, expecially with Blizz-ABS being a complicated 5000+ lines of code script. SDK 1.x wasn't messed up so much, so it might work with Blizz-ABS up to some level. That's why I added "80% compatible with SDK 1.x, 40% compatible with SDK 2.x" in the manual.
@nathmatt: What exactly happens?
