The wiki has led me to believe that a player-persistent variable modified in one campaign can be accessed from another campaign played with the same pilot. Now, either that's not true, I need to file a Mantis report or (most likely) I just don't know what I'm doing. Setting up two variables in different missions under the same name and default value seemed to work for campaign-persistent variables, but the same doesn't seem to hold true for ppvariables.
I've attached a test mod which highlights either the problem or my inability to FRED. Each campaign in it has the same single mission, which continually spews out training messages with a variable's contents. When the '1' key is hit the value of the variable is modified. Warp out and load up the other campaign, which has the same mission and therefore definitely the same variable, however, and the variable has reset itself.
I'd also like to mention that I haven't ignored "Please do not report bugs in the forum" notice on Random Tiger's launcher, but as I've said it's probably some oversight on my part rather than a problem in the code.
