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 Regions Unexplored is the mod with the broken basalt columns, since I'm also running Biomes O Plenty, 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, Regions Unexplored 0.5.5

Close this as the logging may be because of how distant horizon generates chunks for LOD

🤔 could do an experiment to see if it's on us or on how DH does it's LOD's

No it was specifically distant horizon. They were not promoting the side chunks in the 3x3 area for features up chunk statuses which triggered my logging when a feature goes into the side chunks. I removed the logging as it was for basalt features being placed outside 3x3 area but that hasn’t happened in a looong time. This time it was a false alarm due to how distant horizon generates chunks manually for LOD differently than how vanilla does worldgen

Grateful to all who helped track down the issue. I have also reported on the Cataclysm discord as they are doing the same logging. Happy to close the thread as RU is not involved in the crash!

ahhh so, thanks for the info
