Playtest & Locate issues.

[Fract_]

As some may know, trade_portal2_rev1 was recently put onto Trade | US ;
It got many positive & negative reviews, so I decided to re-balance and review some design choices.
I want to be sure that this version is acceptable, I understand I can't please everyone,
But I need to at least know that there is not any map-breaking exploits on this map.
Any feedback & ideas for improvement are greatly appreciated.
