Having issues with saving containers on a Mac. I have future, rusher and meteor and when I added world tools I got a lot of crashing. removing future seemed to have fixed things. after removing future on 1.20.1 it would save the world, but not containers. Updated everything to 1.20.4 and have better luck with saving containers, but not consistent. It registers every container, but not every container's contents was saved in the wdl. Is there a speed issue with saving containers?

Can you try again on latest versions?

Please provide latest.log files of the crashes

What we need is a way to replicate your issue. So some combination or one of a video, world download, or instructions.

I will see if I can get you a world download, and I am working on getting reproducible steps.
