Issue Description:

Game crashes on stratup, it may be caused by another mod, but I am not sure, it is hard to test this stuff with a crappy 5400 rpm $200 laptop for my pack, but the chunks via loadup on the server seems to crash regardless of what world I load up using the biomes o plenty world type.

Additional Information:

• fml-client-latest.log or fml-server-latest.log: server crashlog here

this seems to directly affect chunk generation but also occurs on an existing world that I had before updating my mods in my pack

Biomes o plenty is not mentioned in the crashlog, but yet using vanillafix, it was able to tell me that your mod was the cause of the issue

Closing this because we either can't/won't fix it or it's not an issue in 1.13

I can confirm this happening with build 2400

Getting the same error with build 2402
Does not crash if BoP is the only mod

This issue seems to be the same as #1310

I have done some intensive testing andf it seems that the issue is not related to biomes'o plenty but to NotEnoughIDs-1.5.4.2. Continuing tests though...
I have replaced that mod with JustEnoughIDs-1.0.1-16 and it seems to solve my problem.

@joernott can u provide some details about why its related to NEID

@Pythonic-Rainbow On 3rd of October I updated my WIP modpack (and forge) and things seemed to work fine on my Linux machine in an existing test world. Then I moved to the Windows PC and I got the crash when creating a new world with BoP. The crash report indicated some relation to BoP. At first I did the usual debugging steps:

• Start a "normal world"
• Downgrade BoP
• Remove BoP and related mods
• Start with BoP as the only mod

As step 4 worked and step 3 failed, I knew it must be another mod. So I started with BoP, added the most important mods, taking 3-4 at a time. When I reached NEID and 3 others, the crash showed up again. So I removed them one by one to find out, which mod caused the crash and it turned out to be NEID. As NEID hasn't seen any update on curseforge for quite a while and I recently updated Forge to 1.12.2-14.23.4.2765, I assumed that it was some incompatibility between NEID and Forge or some updated mods. I require the functionality of NEID in my pack, and JEID seems to provide what I need, so I simply switched. Sadly, I deleted the logs and crash reports for the next few tests as this is part of the test routine.

I can confirm your findings. I have both NEID and JEID on my pack @joernott

Omg thank you so much, I really appreciate you helping me out with this, @joernott . I haven't had the time to work on this lately myself. I see that there is in fact an update to Not enough IDs, will test to confirm if it works now...

@MasterBuilder747 that update is nothing worth in terms of this bug
It is just some cleanup of the mod, no real changes

@MasterBuilder747 while its just a cleanup , it may hint that the author is coming back to development. Last changes was back in 2017... I am not sure tho

ok good to know, ill just switch over to JEID then, thx
