Pipe command sweeps properly but Multipipe grabs the end. I’m using the exact same curve. It doesn’t occur with a smaller radius. 0.49mm works but 0.5mm fails in this case.

The Pipe command and the MultiPipe command are very different, are you trying to creating multiple pipes? If so, you can use the Multiple argument at the beginning of the Pipe command.
