unit movement slowdown, orientation wrong

Ave!

... and thank you for a very interesting game :-)

I have noticed a small bug in 2.1beta2. I usually play on maximum slowdown (speed *0.1). However, I noticed that some of the units are moving slower and slower over time. When looking at them closer, I have noticed they're almost vertical (I mean, like they're trying to move using just the rear wheels). I thought they got this way when trying to climb some hills and never got horizontal again, so I tried to direct the units to a slope. Nope, didn't help; neither the ascending or descending slope was able to change the unit's orientation.

But then, on accident, I sped up the game for a moment (until like *0.8) and the units got in the correct (horizontal) position within a second or two. And when I slowed the game down again, their speed was normal.

I have since noticed it again and again; the speeding up temporarily workaround always does the trick.

Looks like the vehicle orientation code can be vulnerable to some... rounding issues, perhaps?

I can get you a screenshot of the vertical units tonight if you can't recreate the problem.

Something like this you're talking about it?

This happens too in the last stable release of the Warzone (2.0.10)

Cheers  :)

Someting like the right truck in the first picture, but in the extreme, i.e. the truck being almost vertical.

I don't really mind the drawing (it looks weird but it's not important); however, the movement slowdown is what really gets me.

This is a known bug, it only happens at 0.1x and 0.2x, briefly switching to 0.3x or higher will "correct" the problem and reset the units.
