[1.3.3159] Double door slowdown issue

[tnekohue]

Any pair of doors adjacent to each other slows colonist down when passing through the second door
This occurs with autodoors, normal doors, even doors that are held open
This bug is present with and without mods, on new or loaded saves, with or without Royalty or Ideology

Thanks for the bug report.  This is actually game behavior that has been around since before 1.0.  I have brought this up with the devs before, and have a report in on it, though I will add your forum thread to my bug report.
