The title says it all, WM will consistently crash when trying to open a group with many devices inside it. This does not happen on the pre-LTE versions of World Machine.
UPDATE: The crashes seem to only happen within macro worlds, regardless of how many devices there are in the group.
I am interesting in solving this but
I can’t currently replicate this bug.
Edit: I figured out the necessary condition to cause this and will have a fix in the next build.
