Bug Report
Dimension specific mobs aren't naturally spawning. I can /summon them but just, in general, they don't spawn in the correct dimensions.

I've launched a SevTech server for me and a few friends however now that we're getting further in we're finding issues with mob spawning. It seems as if all modded hostile mobs have stopped spawning naturally.

The variations of vanilla mobs still spawn i.e. Karate zombie and fallen Soldier's but whenever I'm in the Darklands, for example, none of the specific mobs for that dimension spawn only the vanilla ones. The server is running on normal difficulty with no added mods. We literally booted the pack and left it at that.

If anyone has any idea why mobs aren't spawning id greatly appreciate the help.

Expected Behaviour
Dimension appropriate mobs should spawn in their corresponding dimensions

Possible Solution
fresh install server, import all world data

Steps to Reproduce (for bugs)

I appreciate you made a report for this. Having said that, you ignored the template we provided which gives us the information we need to investigate this further. What version of the modpack are you playing?

Apologies completely looked past that.

My first recommendation would be to backup your current world and update to the 3.1.3 version we released today as a beta. this may help you out as I've been testing and had all of these entities show up correctly.
