Aww man, I think there is a physics_fooluser() routine in LFS to make someone go berserk! I was thinking about this in my sleep ffs! Something strange happened, I know it! I was even commenting about these events as they unfolded to my wife with unabashed enthusiasm, certain I'd stumbled upon an incomplete undocumented feature.... Of course, it didn't make sense that the revs dropped massively rather than there just being no connection between the engine & transmission... And damnit my clutch axis didn't work LOL.
Scapegoat: LFSTweak does wierd things - spread the blame, thank you!
Glad everyone had a good laugh, it's the best medicine!
HEY BOB - .... ah, never mind.
