Hello, I have a server with a lot of creations on it and it seems the map is corrupted and I need to repair my chunks, but chunkster and mcedit are outdated, I need something else to do this with and I've been unsuccessful at finding something that will repair the chunks with as little damage to creations as possible. Anything that does this?
Try to load the map in singleplayer. If you can manage to load the chunks there then maybe you can make a WorldEdit schematic of the creations to paste into a new map.
