Logs, in the event of a crash

No Logs Present

Unfortunately that's the issue. There are no crash logs. Could someone possibly try and recreate this, just to see if it is an issue on my end.

This has only started happening with the latest update.

Can you at least post any kind of other log? The game should log what's going on.

I have a feeling I know what's going on, though. Update all of your mods. This sometimes happens when two mods are using two different versions of mixins.

We still can't help you without a crash report.

Sorry, but what are mixins? The only loaded mods are bewichtment, it's requirments and better portals. All of which should be up to date.

Library used by some mods to do certain tasks that are otherwise impossible. Looking at it, it appears to also be using mixins.

Ok, will this log do fine?
