IK FK does not match with softness after reset

Using mGear version 4.0.9, there is an issue with using the IK FK switch on EPIC_arm_01 and EPIC_leg_01 where the match starts introducing a very big bend with “FK rest T pose” enabled and softness on the host:

You can reproduce this by using “Game Biped Template, Y-Up”, building the rig, and then following these steps:

  1. enter T-pose on the arms and/or legs by going to FK and resetting them
  2. set softness to a non-zero value like 0.5
  3. switch from FK to IK using the right-click menu on the host

Instead of a straight arm or leg, you will see a big bend in the elbow like this.
