Hmm, well without any console error, it is hard for me to find out where the bug is. Unintended word pun hurr durr
And if the error magically dissappeared, it is even harder.
If you have it again, please post the error and/or what you did prior to this error.
As for the flash amount not doing anything, that might have to do with the strange error you received.
EDIT:
Quickly checked the code, found nothing special.
Did fix some potential issues of which i am surprised nobody found them yet.
They involve that people might not have taken damage from poison attacks at ALL when damage amped.
Though nothing has been found that could explain your errors. :S
Did you upload the latest changes to Dropbox as well?
EDIT2:
I sneaked the powersuit in my testing area (kind of hard to hide it with just my jacket...)
I am gonna have fun fiddling with this later on, for sure.
Though only one weapon from all those plans? ;P
Also, still quite some vital animations missing, but at least you made sure to give it an appropriate sitting animation just like all your other models.
I wonder if it has an appropriate headnode (read: hatnode :P) too...
EDIT3:
Of course it has! Army tends to give details like that priority or he just likes to dress his creations up. :P
