Since the latest update my world is very unstable.  It quits rendering and if I go as far as it renders it acts like I am at the "end of the world". The world is 5.5 GB.  Yes 5.5 GB.  It worked fine until the 1.17.30 update.

It is now almost unusable.  It crashes at random.  Functions and commands take a long time to execute if at all.

I started using a smaller version of the world(1.7 GB) and after playing a while it started acting the same way as the 5.5 GB version.  I have to stop development until this is resolved.  Don't want to lose additional work!

The .32 update did little if anything to solve the problem,  I am in a world that is only 300 MBs.
