A bug that really bugs me

I think i have a memory leak on my world editor or something. It won't let me turn on and off water height limits or what time of day it is while in the editor. It won't remember that i wanted the cinematic trigger text to be red and so on. It was fine for a while unill i figured out that i need to turn off water height limits.

To kill three birds with one stone...

What is the 'pathing - cliff height' option for trees?

Can you make your own game data set for the 'Map Properties\Options\Game Data Set' option? How?

thanks,
Tweedle.
