Game crashed due to loading a imported structure.

While attempting to upload a useful .mcstructure file into a structure block the game crashed, even before hand it was out of wack, every time I attempted to upload it all it would give me in return was a air structure which wasnt intentional, I attempted to use /structure delete in order to refresh it but that failed.

After a couple of attempts of uploading and deleting the game froze and crashed shortly after.
