Deleted aircraft still in runway queue

[jpeterson1346]

Using del for an aircraft waiting on the runway successfully removes it from the screen; however, any subsequent aircraft wanting to takeoff on that same runway will throw back a "cleared for takeoff, number [#]...behind the [deleted aircraft]...," thus rendering the game unusable.

Ex at JFK: AA1, BA2, DL3, VS4 on the apron looking for taxi to a runway. Meanwhile CX10, EK11, and AF12 on approach for runway 31L.

• CX10 ILS 31L // followed by a valid intercept; 10 mi final
• EK11 ILS 31L // also successful intercept; 14 mi final
• AF12 ILS 31L // successful intercept; 18 mi final
  [then, ]
• AA1 W 31L
• BA2 W 31L
• DL3 W 31L
• VS4 W 31L
  [all my departures are headed to 31L and have valid SIDS and climbs]
  [by this time, CX10 is on a 2 mi final, EK11 on a 6 mi final, and AF12 on a 10 mi final. AA1 is waiting on the runway and to avoid an incursion, I issue]
• AA1 DEL // Aircraft then disappears, flight strip gone.
  [That's good and all. So, let's say the Emirates and Air France land successfully on 31R after I clear them for the parallel; the Cathay lands successfully on 31L. Now I can roll out my departures]
• BA2 CAF CVS TO // (on 31L)
  [and here's what I get back]
• "Speedbird two, cleared as filed, climb via the SID, runway 31L cleared for takeoff, number 2 behind the AA1."

Since AA1 is no longer on the field nor in my flight strip bay, there's nothing I can do and BA2 will just sit, waiting for AA1 to depart (i.e., forever).

Anybody else have this issue?

Here's an example in practice:
1.

The American flight says the following:
"AAL241, number 1 behind JetBlue six thirty eight"

The Delta flight on 4L (DAL2972) says:
"DAL2972, number 2 behind American two forty one"
