A few things;
I) There's a small hop when exiting certain interactions, not gamebreaking but it didn't happen to me in 0.8.0.
II) Kerfur Omega now damages the ATV, I just got off the ATV and Kerfur spawning in it and walking out took it from full health to 56.
III) While not a bug, with Kerfur now dropping items when mounting the ATV, it would be nice to have a toggle option in the interact menu to have them swap between riding with and walking behind.
Other than that, great update.
