I couldn't get a 16384 world to finish on a t2.2xlarge (8cpu 32G ram). Would get to the "Generating Detail Data" part as described above.. Sit there maxing out CPUs for about 4-5 hours and then silently die. Tried twice with the same result. A 4096 world finished generating with exactly the same serverconfig.xml (except world size) in about 20 minutes. With the number of people I play with A 4 and 8K map is really just fine.. But I kinda wanted to experience the expanse of a 16K world. Changes to RWG have been positive so far, other than the 16K silent crash.
