Fixed the version compatability, thanks for the heads up J!
Im dillegently getting back into this, and resolving this crash issue... interesting that the different MIS files make a difference, as I always thought the MIS weren't read on save load.
There seems to be a pattern there with wind and Fog being 0 for the "corrupted" campaign files.
For reference, the log file contains the values written to the campain files as follows:
Now, Clouds, Rain, Fog, WindSpeed, WindDir, CloudsRand, PrecipRand, FogRand, WindRand, Interval, SelectedMonth, Season, InMedSea <==Edit: removed PHP tags for better readability
That's snipped directly from the code that writes the log entry.
Thanks for the additional info Lucky, we'll get to the bottom of this.
