Exported tileset lost all data

[NewAgeSteel]

So I just spent hours on a tileset, then I went to import it, after I imported it, I accidentally clicked export and it exported my file with nothing on it. is there any way to get this back? I don't see why exporting something should make it delete all of the data on it. whats the point of having a feature that exports something just to delete all the data on it?
anyone know if theres a way to fix this?

Exporting a tileset shouldn't remove it from the game files, so there should still be a copy of it in there. If not, then you'll probably have to re-import it.
