even after the latest update it still gives me an error on every version except 1.5.4 and prior. it gives me this error
""Error while running setup for entity prototype "one-to-one-forward-pipe" (pipe-to-ground): next_upgrade target (niobium-pipe-to-ground) must have the same fast_replaceable_group (pipe != pipe-to-ground).""

A) Can you post this on Git (https://github.com/pyanodon/pybugreports)
