So since afew days i get strange behavior and i think its because of OSRX.. I have alot of diffrent Tanks and drills on a rover, and only this rover brings the game nearly to freeze. The log says: [EXC 15:27:58.866] IndexOutOfRangeException: Array index is out of range. ORSX.ORSX_AnimationGroup.get_ActiveAnimation () ORSX.ORSX_AnimationGroup.PlayDeployAnimation (Int32 speed) ORSX.ORSX_AnimationGroup.SetRetractedState (Int32 speed) ORSX.ORSX_AnimationGroup.CheckAnimationState () ORSX.ORSX_AnimationGroup.OnLoad (.ConfigNode node) PartModule.Load (.ConfigNode node) Part.LoadModule (.ConfigNode node, System.Int32& moduleIndex) ProtoPartModuleSnapshot.Load (.Part hostPart, System.Int32& moduleIndex) ProtoPartSnapshot.Load (.Vessel vesselRef, Boolean loadAsRootPart) ProtoVessel.LoadObjects () Vessel.Load () Vessel.Update () [EXC 15:27:58.867] NullReferenceException: Object reference not set to an instance of an object Part.ModulesOnStart () Part+ .MoveNext () [EXC 15:27:58.867] NullReferenceException: Object reference not set to an instance of an object Part.ModulesOnStart () Part+ .MoveNext () [EXC 15:27:58.992] IndexOutOfRangeException: Array index is out of range.

It was working fine... no updates to ORS since then and suddenly this happens.
