Hi I have noticed a issue with the mod ( or possibly a mod conflict). whenever me or one of the players on my server die in the nether a grave stone is spawned, this is as it should be. but the skeletons that spawn around a grave at night continue to spawn until the server crashes due to insane quantities. as a side note this only seams to occur in proximity to nether fortresses.

I guess it is wrong mod. Is OpenBlocks spawns skeletons? It most likely https://github.com/NightKosh/GraveStone-mod problem.

Well, our graves DO spawn skeleton (it was surprise to me too). Though it limits spawn rate to about one every minute and won't spawn, if there are more than 5 other mobs nearby. And I see no way it can work differently in nether and in vicinity of fortress.

I guess I can always add option to disable that.

That would be very helpful, thank you for your rapid response
