RoverDude, first I want to thank you for the extraordinary work you've done to make this game more fun for me - I have installed and use pretty much all of your mods, and they are pretty sweet. Unfortunately I too have experienced a bug involving WarpDrive. It appears to have something to do with a SOI change. If I switch SOIs either by loading a ship in the space center or moving through it on another ship, then the bug occurs. Everything seems normal until I try to timewarp. Once I've started timewarp, the ship seems to freeze in space - nothing changes whether it be velocity or position. I tried to uninstall Warp Drive to fix this, but the game crashed every time I switched to my ship travelling from Kerbin to Mun with a SOI change in the future. Reinstalling it fixed this, but the bug still exists. Another case that just occurred - I was launching a ship, approaching my apoapsis, around 85k I started to timewarp, and the ship froze - but now the apoapsis continues to increase whilst the ship's velocity stays the same (as does its position) Thanks again, looking forward to seeing more of your work in the future through 0.90 and beyond.
