I've got a custom mod pack for my friends and I and have been having a problem where only a couple of different biomes are spawning in a world. These couple of biomes differ from map to map, but its usually around 7-8 biomes that are repeated throughout the world. I have tried updating the mod, checking the configuration, and using a different seed, but it always does this. I can't tell if there is some kind of incompatibility with another mod or if its the mod itself but it gets quite annoying.

If anyone had any info or solutions on this problem they would be greatly appreciated.

do you think that if i would just go ahead and start the server from the provider it would work since its on a different machine? Or is it the actual modpack problem. Sorry if im asking a stupid question

A couple of months ago I had a modded server for my friends and we ended the subscription. Now I am trying to set it back up and I'm trying to test it on my pc before I subscribe to the hosting company. I would greatly appreciate if anyone could read this crash report for me and tell me what the problem is. I'm guessing its a problem with java, a client-side mod issue, or a crashing mod so if someone could clarify I would appreciate it.

Quote from Exalm

Hardness: I tried to make it, but I don't know what changed. Making redstone ore "effective block" doesn't work, and block itself didn't change.

Old creepers/skeletons: Yes, but later. Currently NBXlite has weird bug with liquid generation, and I just see no reason for it. For example, generate Beta world with gargamel seed. Valley should have 2 water springs, but it has just 1.

For old generation use NBXlite.
