Tileset editor error when have more than one frame.

When I open a Tileset and add a second frame to a tile, when I go in "Edit Frame" -> "Edit Image" (using Pencyl), after I edit the frame and save, Stencyl gives me an error and every tile disappears, leaving just the one I was editing.

It doesn't happen with one frame tiles. Or if I use "Edit Frames (External)" option.

Image and log attacheds.

Thanks.

Ouch... it is painful! I have the same problem. All my tiles disappear and the game can not be built:

I don't saved, so no injuries to the game, just lost the tile I spend some time editing.
But it's annoying, I don't like to edit the frames at once, but separately...

Your error seems different of mine, you get all these on Log Viewer?:

Yes. 

Should be fixed in the just released update of 3.2.
