#9707: PQ1AGI: Segfault during restore via GMM at cards game
---------------------+----------------------------
Reporter:  waltervn  |      Owner:  (none)
    Type:  defect    |     Status:  new
Priority:  normal    |  Component:  Engine: AGI
Keywords:            |       Game:  Police Quest 1
---------------------+----------------------------
 When trying to restore at the cards game using the GMM (at a time where
 the game does not allow it via F7), I frequently get a segfault.

 Steps to reproduce:
 - At the poker screen, type 'ante'
 - Wait a few seconds
 - Open the GMM
 - Restore a save game

 Backtrace:
