I have a world seed ("co-ordinates") from December and when I try to use it to start a new game it creates a world which looks nothing whatsoever like the world it USED to generate.... Please either fix or tell me how to convert the old seed to the (apparently) new format.
Steps to Reproduce
The seed is SNDST-A-1209266338-0 and I got it from a text file from December I used it (in January) to create a world which looks like the first picture "Hopeful Hovel" (which reports the same seed) It now creates a world which looks like the second picture "dump" (which still reports the same seed)
This issue has not been confirmed by a developer yet.
