it worked for you because u didn't supply a name...
"addbot <skill> <team> <model> <name>"
[edit]
okay this is hard i can't figure out how to do this..
if i use StripClanTags it'll even strip out parts of the person's name if it has { } or ( ) or [ ]
as you can see i am a very inexperienced coder

I've gotten too used to PHP

[edit2]
it's only supposed to work in the right order and inorder to supply a name you MUST supply everything else...
and that leaves me to question why that 2nd one worked...

also when i tried it i supplied it with addbot <skill> <team> <model> <name> and it worked perfectly fine...
