Map Oddities... Chunk errors?

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?

 

Nope. Which CB# you use? Plugins that affect world gen?

 

We started on 818 I believe - we're now on 920

 

did you use in this zone Worldedit with //regen command?

Beacuse //regen generate chunkerror if the chunk is unloading.

 

I didn't use //regen - these were loaded like this when we released.

 

It's possible that //regen was used around these chunks at some point and it occurred.
