I've been running dev builds of 1.0/1.0.1 for a while now and today switched to the RB of 1.0 server. For some time I've had a problem with hostiles not spawning (animals spawn fine as do mobs from mob spawners underground). If I'm 'lucky' maybe a 1-3 mobs spawn in a game weeks time and that is maximum. Configuration is correct afaik and I've tried to remove all plugins to see if that affected spawning with no result. Anyone know how to fix this and have the hostile mobs spawn again? Any advice on tracking this down or how to fix it would be welcome.
