Not wholly sure the cause here. But updating version and copying over the new configs generated seems to cause generation of a new world to hang, and the cause is that the server has crashed.

EDIT: deleting my modified configs (both the json and the cfg) prevents the error. I'll try to figure out which option messed things up.

I see what's happened..

If the geolosys_ores.json file is missing an ore entry, Geolosys itself never tries to re-initialize them (I should, I know, and I shall). So it could be that if you had an old version of the geolosys_ores.json file and I added a new ore - like Beryl - then it would be referencing berylDimBlacklist, which wouldn't have been read in from the JSON and would therefore be null.

Yeah, I re-added my changes, re-testing the world gen a couple at a time and it worked. It certainly looks like the json got invalidated, and the main problem with having a single json file for config, as I've learned from my own projects, is that if one entry is messed up, the json-reader often returns null for the whole object. XML of course has the same issue.
