Some more notes:
As others have mentioned computer CTDs on exit from patch 88. (Code C0000005)
My CTD (actually hard reboot) with certain ground clutter in the beta3 terrset03 terrain is gone.
Bouncing for wheeled vehicles (well at least the Jeep) seems a tad strong, but it would also be nice if it was better correlated to the visual appearance of the terrain patch you're driving over. For example, the baked flat ground in the lemon grove is very bumpy in a Jeep. I suspect this fine tuning will come later.
On bumpy ground my Jeep flipped upside down and continued to bounce forever (unless I turned the engine off), finally sinking through the Earth. When below the ground, if you are perfectly upside down, you can actually drive off, upside down, with the wheels running on the underside of the ground. Only the dust you kick up is visible. When you get to a non-bumpy terrain, say a field, you flip back over into the real world above ground. This was reproducible in all terrains.
Had a case where my vehicle engine sound disappeared entirely; even shutting off the engine and restarting didn't work and neither did re-spawning a new tank. (Engine was functional and I could move and I could hear the tracks.) I had to restart the program.
PT torpedoes don't make any splash sound when they enter. (But maybe I'm hallucinating that they make a splash in AH2? If so, change this one to a wish I guess.)
Oh.. and my clock doesn't tick.

I feel left out.
