Kerbal Space Program

Following Steps outlined here(http://forum.kerbalspaceprogram.com/threads/75586-Master-Thread-Unresponsive-Kerbals-in-EVA?p=1072667&viewfull=1#post1072667):

The Part in the post:

MODULE {
name = KerbalEVA
isEnabled = True
state = Ragdoll

My 'state' was: state = Idle (Grounded)

Changing 'state' to: state = Seated (Command)

Made them work again.

The Summary of the Post that fixed the issue:
Do a file Edit of the 'Vessel' (in my case Kerban Rover 4).
Find the Part that's name is 'kerbalEVA' (crew will equal the bugged Kerbal)
Under that Parts 'Module' there is a module with a name of 'KerbalEVA'
That Module will have a state of something undesired (Maybe Ragdoll or Idle (Grounded))
Change that state to something desirable (in my case Seated (Command))

Colliding a Kerbal with a seated Kerbal causes this issue!
