Don't really know what to do to cause it to happen, it just happens every time I load a previous world or try to start a new one. The world is created though.

Search function does not allow for previous versions to be selected when searching, at least from my end.

Also, antivirus is currently fully disabled, should have no reason to be interfering, and oddly does not happen with ANY other version, snapshot or otherwise for me.
