The rope created by Capsure&Joint is easily dispersed (T-T)

When set first dynamicRigid Kinematic and move it fastly，the capsules will be dispersed.
Also may be：pxvec3 pos = getGlobalPos(), pos is (nan,nan,nan).

see in the pciture:

Try increase solver position iteration counts. The default is far too low for things like this. You may also need to reduce the timestep if moving quickly.

thank you for your suggestion! increasing solver position iteration counts is effective. But when I set one of the capsule to kinematic mode and move it by setKinematicTarget(), it is more likely to have vertex position (nan, nan, nan)，do you have any suggestion about this?
