What's the issue you encountered?

Hi there. Had an issue last night where my game crashed while in the Nether. No crash log, but I checked my latest.log and I was surprised to find it was over 3GB in size. I had to open it in Firefox because it was too large for either Notepad or Word.

The cause of the massive log file was apparently the same few lines repeating, like, a million times.

I can't confirm 100% whether Biomes O Plenty is the mod with the broken basalt columns, since I'm also running Regions Unexplored, so I'll be making a report on both mod pages.

You can see here for someone else reporting this error. Repurposed Structures dev says it needs to be fixed on the world gen side rather than just suppressing the log error.

Obviously can't upload the full log here, but happy to provide any other info as needed. I am running Forge 1.20.1, Biomes O'Plenty 18.0.0.592. Appreciate you say that older versions are not supported, but if this is a BOP error I assume it will persist in both versions. If it has been corrected in 1.20.4 then please do let me know. Alternatively, if BOP does not include broken basalt columns, feel free to close this report.

How can the issue be reproduced?

That has nothing to do with BOP. We don't use the basalt column generation for anything.
