Legacy rails are generated in blueprints

[yincrash]

I believe this is just because factorio detects the blueprint version and automatically changes all "straight-rail" entities to "legacy-straight-rail". I think just the factorio-blueprint project just needs to be updated to update the version code so rails are generated properly again.

For anyone else who finds this post and want a temporary workaround, import your blueprint into factorio, then export your blueprint from factorio (which will have the new "legacy-straight-rail" entities), then import them into the cyberchef link here - https://www.reddit.com/r/factorio/comments/1ge8xfa/how_to_easily_replace_all_your_legacy_straight/

An easier way could also be to have cyberchef only replace the generator's blueprint version code.
