After you have all the perks there's an invisible perk where if you drink it you cannot buy anything, reload, run, or anything
  but shoot and walk around.

you can pull the one out of my perks pack. All you would need to do is add the perks you want to be able to get to it, into the array of perks for wonderfizz

level.wonderfizz_perks = [];
level.wonderfizz_perks[ 0 ] = "specialty_quickrevive";
level.wonderfizz_perks[ 1 ] = "specialty_armorvest";

etc

It failed to load the bottle weapon file, thats why this happened. It got stuck waiting for "weapon change complete"

cool, could use the whole pack to make it easier, but odds are youll hit limits and need to comment out some stuff to make more room, let me know how you get on ;)
