I have been trying to "break" the latest build of ACP 8, testing Flat Plans exposed the following issue:

State: Light Level "Very Light" - (i.e. "Unsafe" state)
Dome Closed

Using One-Time Flat script - setup simple plan for 2 flats
Plan runs with no problems up to the point of "Closing the dome/roof"
It appears that the Flat plan assumes the roof/dome is open.

The Roof was already in a closed state when the plan was started - I waited for 3 mins for the script to continue then aborted. After the plan was aborted the System Display indicated the Roof state was "Open", when in fact it was closed at the beginning of the plan and remained physically closed after the plan was aborted.
I have not seen this behavior before, Roof status has never been reported incorrectly.

I reran the same test, to verify, and got the same results.

In neither test did I wait for a _possible_ timeout for the dome closing command, I assumed that there was no built in timeout.
