1.9.8 stretched hinges goes mad

Especially on low-density objects...

Basically this is a problem of precision - two forces who's difference should be zero, but due to rounding errors become something substantial, only because of the sheer magnitude of the original error.

There are several ways to solve this, pick one:

A) Use heavier objects.
B) Use weaker hinges.
C) Use double precision like 1.9.7 (speed penalty).
D) Use an imprecise solver (like 1.8.5).
E) Don't build scenes lacking a well-defined solution.

So another words - you don't plan to fix it
