Since we have used automatic chunk-trimming of chunks that have only been inhabited for very short periods of time - in order to reduce world size and free up chunks for modern world-gen/features -, it was decided that if a chunk has not visibly been modified then we can use WorldEdit's chunk-reset command to get new generation (within reason). Well at least that's how I justified it to myself, idk how much Aj cared he just wanted a trial chamber that was not really far out innit.
