Map editor problems!

[Goomba]

Hey guys,

So I've been making a map in the old map editor. And wanted to add some more things but the object limiter didn't let me to. So I converted it to the new map editor.

I've been editing some things, saved my map.. and I openen it again. And all my changes were GONE, my map didn't save at all!

And there's another thing when converting my map: it fucked up my spawns (check screens).

Hope you can help me out, this new map editor sucks balls if you ask me
