Kerbal Space Program

The KAL-1000 "play position" action group behaves unexpectedly: when connecting one KAL to control another KAL via the play position it seemingly connects the relative play position of both KALs rather than accepting the input of the control. Thus, setting one KAL "controller" to set another KAL "subordinate" to e.g. position 0 it instead plays subordinate from 0->1 in tandem (i.e. not respecting the play speed or track length of subordinate) with the play position of controller. Changing controller priority has no effect. Editing KAL in flight has no effect. The value of the "play position" setting has no effect.

The effect can also be daisy-chained (e.g. Controller sets play position of subordinate, which in turn sets play position of "additional", and all three KALs will play through in tandem when controller is activated).

To recreate, simply add two KALs, using one to control the play position of the other. The effect is recreated in both the VAB editor (by "scrolling" through the controller play position) and in flight.
