Blender Version
Broken: Blender 2.76.8 Hash:257268a
Worked: Blender 2.76b

Hi!
It seems that blender game engine dynamic, softbody, character physics work like slow motion! Please compare attachments in 2.76b and 2.76.8 (latest build).
Horse falls down very slowly and if press spacebar, goes to infinity!
In softbody, flag is slow motion!
Character physics is buggy, too. but I didn't include in attachments.

horse(dynamic).blend

Hi,

First bad commit:
commit 3dbc123061
Author: Sybren A. Stüvel sybren@stuvel.eu
Date: Fri Oct 9 12:12:13 2015 +0200

  BGE: allow setting velocity to zero in a motion actuator.

  The motion actuator goes out of its way to prevent setting zero velocities,
  which should actually be supported. This patch just works around it as a
  first test. We should investigate whether the flags
  `m_bitLocalFlag.ZeroLinearVelocity` and `m_bitLocalFlag.ZeroAngularVelocity`
  are actually needed/desired at all.

  One of the issues that's already visible with this simple change, is
  that objects aren't actually frozen but still move a little bit; see
  test with {F241908}.

This is discussed in D1545 too.

I actually prefer reverting 3dbc123061 over @panzergame's patch, which adds even more branches to a logic brick that already tries to do too many things.

For now I'll revert 3dbc123061 in anticipation of a decision in D1545.
