Notice a weird beta hole, save and quit wouldn't bring the chunk back. Had to delete the chunk in Mcedit in order to fix it.
Side Notes:
1. in Mcedit it showed the terrain as if it was generated differently in the beta hole, terrain gen code cross over bug maybe?
2. Found 2 more beta holes that needed fixed, chunk loading seems off.
3. All item frames losted there items/maps, and all chests lost there items aswell after fixing the chunks by deleting the chunks in mcedit. None of the deleted chunks contained item frames or chests.
Was this world freshly created in the snapshot, or pre-existing? If so, what version was it originally created in? Can we also get the world seed (command is /seed) and sample coordinates (F3)
