Scenario Loading CtD Stack Trace

[Vehem]

I pulled the following from the crash dump for the scenario loading - I'm not sure if it has been seen before, but it points nicely to a specific area of the code as potentially being the problem, namely CvPlot::getX(), being the only item on the stack at the time. As it's an AccessViolation, it looks as if the memory assigned for storing the requested plot (or possibly all plots) has already been released (map array unloaded), but is being called on for some reason.

Might help - might not, but the stack traces have been handy when Xien has been poking at DLL problems previously, so I figured it couldn't hurt...

Heh heh. That's the first thing that I looked at once 040 was done installing So the good news is we got the same function pointed to when we did a trace.
