Spotted this in the console, so reporting it.

Could you please report more information on your setup? Like a list of mods installed with the corresponding versions. Which Minecraft version? Judging from the log you didn't experience a crash, so what were you doing at or shortly before the moment the error appeared?

We can look into removing the log errors, but this is completely normal. Thank you for the report.
