Blech. You clearly got a great result in the end, but it seems that any thick section of resin can have uncured liquid lurking therein. Has anyone had luck treating the stuff to cure it? What a pain. This could account for hull sagging as well.

Reminds me of Shapeways, which used to have a whole section of their website devoted to complaints from people who tried to paint 3D printed models, only to have the paint decompose those early resins.
