Version duplicate

There is a duplicate rd in the launcher. The version called "rd-20090515" is a duplicate of the version called rd-161348

This problem can be noticed because the version named rd-20090515 has exactly the same gameplay.

 

I would like to know why this happened and how, because rd-20090515 cannot be found anywhere at the moment. I would really appreciate if you replaced it with the actual rd-20090515.

 

 rd-161348 was made a day after this version and it is flat with a stone floor. rd-20090515 has more complicated world generation.

See the pictures under from both. 

 

Thank you,
