tl;dr: is there any good way to repair corrupted chunks without losing a build? My server's co-owners and I have always been extremely careful when using WorldEdit. We always cap the number of blocks per copy/paste, constantly restart servers, so on and so forth. All except for one build. One big, important build. Somewhere along the line the build got corrupted. Using MCedit we have been able to fix lighting issues making the build accessible, but you can tell the area still has issues due to fps drops. Luckily, it is still usable but it is definitely noticeable. I do not completely understand how schematics work and therefore I am unsure of what my options are in regards to fixing these issues. For example, would I be able to save a schematic of the build, reset the affected chunks, and then -safely- repaste the build or is the corruption now tied to the build itself? Is there something else that could help here?
