Do you think there is any chance the crash is caused by RandomPatches?

I'm asking because I know the mod handles things related to NetHandlerPlayClient.handleTimeUpdate.

It doesn't seem to have a lasting effect, and I'm using VanillaFix so it basically doesn't have any effect, but I still can't track down the cause.
Reproducing it is difficult, because it happens at random times.

Thanks for any feedback!

No, this shouldn't have anything to do with RandomPatches.

Do you have a clue regarding what could be a possible cause, anyway?

The client is trying to handle a time update packet while not in a world. The game tries to access the current world, which is null, so a NullPointerException is thrown. I don't know what could be causing this.

Thank you!
