Incorrect switch (possibly other track-related?) object placement

Have observed this on many routes

Route here is NYCTA A line from here

Latest unaffected build is from June 2

Yeah, we're aware, and have been for a little while.

TLDR:
We first discovered an issue with an object using a negative 180 degree flip, and made a change which sorted this.
Unfortunately, as is always the case it broke some other bits, which we didn't discover till later, and promptly uncovered a more serious math issue


There will hopefully be a fix shortly (S520 has been working on this, but he's not been available this week)

Some rather convoluted discussion in here:

Latest build fixed that, thanks
