You are not alone. After the new pond update, I noticed the same thing. Sprig and Acorn fence blueprints no longer join (snap)
together in a straight line; platforms shift at a slant and do not snap correctly to existing platforms, etc. Laid a blueprint
of the gate and larger weed stem borders yesterday (Friday) and they seemed to have worked. Some single items like
containers don't shift, while the spinning wheel does. Love the new update, but this glitch makes building anything
impossible. Hope Obsidian notices this problem soon and sends us a fix. Until then, I'll keep trying to clear that
Wolf spider from its den and try not to keep dying. Should keep me busy until they solve this problem.
