In the autorouting dev server if you click over to sample 40 in single-trace it will spend forever loading, we should turn on debug and see why it's freezing (export DEBUG=tscircuit:*)

This might have already been done via: Add Debug SVGs for snapshot algorithm development, fix duplicated routes returned from autorouter.
