#10014: TITANIC: Crash if loading (using GMM) saved game in-between Deskbot and
Bellbot
---------------------+------------------------------
Reporter:  dafioram  |      Owner:  (none)
    Type:  defect    |     Status:  new
Priority:  low       |  Component:  Engine: Titanic
Keywords:            |       Game:  Starship Titanic
---------------------+------------------------------
 ScummVM: 1.10.0git-4120-g720e146
 Game: Titanic ver. C
 OS: Win7-64

 In-between when you get your SGT room from the deskbot and you talk to the
 Bellbot there is a brief 3 sec time period in which you can save/load
 using the GMM. Saving works just fine here. If you load a game then it
 will crash.

 In the original game there is no hour-glass during this period, but you
 still can't load/save.

 You can prevent the user from loading/saving during this period to fix
 this, but identifying the root cause may also be good since loading at any
 point in the game doesn't seem like it should crash as long as the saved
 game being loaded is valid.
