As discussed in IRC, correct fix would be just do nothing if current frame isn't lastframe+1: kind of if lastframe+1 != CFRA) return result; thing.
Will check this tomorrow and if it'll be still some issues will assign to you, Daniel =)

Hi,
Got such patch for this issue: http://www.pasteall.org/27963/diff
It works but maybe there's nicer way to find out previous frame simpulation is calculated for.

Daniel, maybe you can glance at it and say if it seems fine for you? If so the same thing can be done for softbody too.
