If you could describe the problem in more detail, then we may be able to help.
Well, i flatened the hills a little bit with the Smooth tool, and it gave it a nice look.
Then after i changed the dirt path a little bit, by cleaning up the edges and stuff like that.
Then i pressed "Save Mission.."
Nothing really happened, no lag, but i tryed to save it again just to be sure but i clicked on "Save Mission..." and nothing happened.
Then i left the game, restarted blockland and started my SP server with my map.
then the map was the same again.
So i did the same again and then i pressed "Save Mission As.."
I located kenkoslopes.mis and clicked it twice and nothing seemed to happen
no lag at all.
Then i left the game, restarted blockland and started my SP server with my map.
then the map was the same again.
There wasnt any other KenkoSlopes map in the list, only that one.
and now my hands hurt after typing all this.
