Got back from vacation and the bowls were
trying to turn into pretzels, with rim cracks of 1 inch depth.
Re rounded one and threw it into LDD overnight. Yesterday I tried to
finish it, but it started moving while sanding. Turned into a potato
chip instead of a pretzel.

Looking at this bowl, it's not particularly surprising it has moved so
much as it appears the grain is going in multiple directions plus the
presence of two knots. I don't know the shrinkage characteristics of
straight grained, clear eucalyptus, but the "features" in your bowl
certainly don't help matters.
