Unlike most of the crashes I've seen already reported I'm not seeing any mod information?

List of mods in our pack here. I managed to do a full profile once but since then I've only been able to profile the overworld, when in the overworld. Any advice on troubleshooting would be lovely.

Wild. Before I saw this response I tried from a fresh install of the same build and it's working just fine - even up to a chunk size of 1000 😕

I'll try and reproduce and get you a full log today but if I'm unable to I will close out this machine elf of an issue.

Could you provide a full log? Might be somewhere higher up.

You can try profiling different dimensions when you are in those dimension to track down if it is a specific one.
You can then add the ID to the blacklist in the config.
