Kerbal Space Program

The Issue

Some of the action group actions, notably the toggle states, do not operate on the first use of the action groups they are assigned to.

This affects the following:

Toggle gimbal - all engines.

Toggle motor - all wheels.

Toggle steering - all wheels.

Reproduction

Assign these commands to an action group, they will fail on the first keypress after loading, but will function normally after that.

Provided is a Scenario file with an affected craft, on the first press of the "1" key the solar panels and docking port will open and the small engines will activate, on the second press the panels and port will retract, the large engine will lock the gimbal and the wheels will toggle their motor and steering states.

Implications

This issue can cause an action group to become out of synchronisation if several actions are combined in one group, potentially causing gameplay problems.
