I noticed that after a few days of going 'public' with our latest map - around the areas there were very strange things occurring. I'm not quite sure how to descibe it - so I'm just showing you in a few random places. It appears that the errors go by the 16x16 chunk relationships but every so often it misses a block. A simple //regen fixes this, though I think theres some underlying chunk issues going on here. Has anyone seen this thing happen before?
