Lost Tilemap functionality after reopening project

[Artheus]

Hi guys,

So I'm just learning how to use 2D Toolkit.  I made a tilemap last week and started making a little map with it, everything went fine and I learned how to use tilemaps.  I open up the project today and now clicking on the tilemap object does nothing, as in I can't paint any new tiles.  Clicking on paint, cut, etc. does nothing.  It's like Unity is ignoring it's functionality.  Everything works fine if I make a brand new tilemap.  Any suggestions?

I think I figured it out.  I had two tileMapEditorData files with the same name but in different folders, I deleted one and it seems to be working now.

Ok, upon reopening the project, it still didn't work.  I deleted that tilemap object and remade a new one, but this time I created the tileMapData and tileMapEditorData in the Assets root folder.  I haven't had any problems with it so far, even closing and reopening.  I'll report back if anything breaks again.
