Additional Context

Found a cool generated portal frame, started building a base, entered the nether for some resource havesting and this happened.

I can even provide the seed and the portal frame location which I used which caused the crash if need be.

Sorry this issue came back up! I wasn't able to replicate it before, but found what seemed to be causing the issue anyway. I'm looking into it again to see if I can find another instance of the error that I missed previously. I'll keep you updated!

Could you do me a huge favor and replicate the issue with this mod installed? That should give more information if the crash still occurs. If it doesn't occur, it's possible that the crash is caused by this which I believe Cyanide should fix as of version 2.1.1. Thanks in advance!

Well I did and found out something interesting. https://pastebin.com/7YrX4SPF

I think this will best explain it.

Interesting! Well, I’ll have to figure that out, but it might actually be a Mining Master issue. I’ll have to figure it out, so I’ll leave this issue open here for now until I determine which mod is actually causing the issue. Thanks for reporting this!

I've done some personal bug testing and I've found that both terrablender and moonlight cause crashes with nether generation

Do you mean in conjunction with Infernal Expansion or on their own? There is an existing Vanilla bug that could cause these exact crashes. I haven't yet had a chance to look at Mining Master to see what could be causing this, but the crash does seem to be a strange issue that shouldn't be occurring (especially since the Cyanide log seems to say that the feature should be before itself if I'm reading it correctly). It would be interesting to know if TerraBlender is having similar issues as well.

The issue has been identified and there will hopefully be a fix soon. There's a possibility Forge themselves may rework something that would fix this issue, but, if they decide not to, we will fix this on our end. Thank you for your patience!

When the fix is made, is it possible to update the world's data pack so I can keep the world?

I'm not 100% sure, but I'd assume there is a way, yes. I've never attempted it, but I think there should be some way to do it

I might have run into this as well, the pastebins are expired so I can't tell. I had a feature cycle crash on attempting to enter the nether the first time.

Edit: False alarm, it was Geodes doing it for me.
