A few of my older projects that were fine for the past couple of years are failing with " nodes failed to load " message. Although they appear fine in the viewer after going through loading.
As a remedy, I tried to copy/paste the design into a new blank TinkerCad project. The " nodes failed to load " persists. A very short thread here mentions the similar issue after TinkerCad put a tighter coda on number of polygons. Is this true!? Are there any workarounds !?
