Subject: Instantly set turnout paths when loading state
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=08dea8dfcf923e9296bcd3910455540895d0439b;p=r2c2.git

Instantly set turnout paths when loading state

Vehicles are placed immediately and will follow turnout paths.  Having
them in the wrong places confuses the route planner.
