When you make your scenario, how do you bring it back up to edit the original?
When I open it I notice it says My Game, is that the same file?
When I am done making the park and want to download it to this site, do I put it in parks?
How do you make it stop raining?

Save it different, so when you make a scenario save it like "park1"
when you play your scenario and save it then as "park2" your original is then protected.
Your saved scenario goes to new scenario`s, when you save it in the scenariocreator.
When you save it in a normal game, it goes to scenario map.
I always open the created scenario in the normal game, then i save it directly and then give it a different name so its easy to find and upload it here.
if you put the climate into dessert, it wont rain. (scenariocreator options)
