Vehicle sign change from 12.1 to 14.1?

[Sigil]

I had a tank-style Vehicle implementation working in 12.1, but when I upgraded to 14.1, everything seems reversed. Pressing forward makes each tread go backwards, the tank spins in the opposite direction than the inputs, etc. Did I miss something in the change history?

Edit: Yes I did. Found the note about reworking vehicles in the 13.0 change log.

Yea, sorry about that; I cringed when I saw that bug because I knew it was going to be a strange breaking change. Hopefully the pain was worth future users not having to wonder why the vehicle accelerates opposite to its forward direction
