When running the profiler on a module, I noticed that one of the counters had wrapped around as seen in the quote. Damn weird value for an overflow, though... |

I don't have made the plugin, but I can imaging that if you run your nwn system a very long time without restarts that the profile counter will wrap around as its just a 32 bit signed integer (based on the size).
What you should do while profiling is doing it only a short time. This way you prefend overflowes like the one you are experiencing. |

it's a minor bug for now as you can add 2^32 to that and it'll give you the real number, but it's worth concidering moving it to a unsigned long long, aka uint64.
Ok, can't be bothered to make a patch, as there's no CVS for nwnx2/windows :) |
