#10716: SCI: LB2: Act 4 not initialized correctly (floppy 1.0)

Reporter:  sluicebox  |      Owner:  (none)
    Type:  defect     |     Status:  new
Priority:  normal     |  Component:  Engine: SCI
Keywords:             |       Game:  Laura Bow 2: The Dagger of Amon-Ra
----------------------+------------------------------------------------
 LB2 Floppy 1.0 doesn't initialize act 4 correctly when triggered by
 finding the dagger, causing the act 4 scene in Yvette's to lockup the
 game.

 I've written a script patch for this and will be submitting soon.

 Attached are two saves right before the end of act 3 to test and compare
 both ways to end the act.

 To reproduce:
         1. Load the save that's in the vat room
         2. Climb vat 13, this will trigger act 4
         3. Go upstairs to Yvette's office via the staircase
         4. You end up back in the hallway without Olympia and Steve and
 input is forever disabled

 You can use the debugger to see what's going on. "vv g 111" will display
 global111 which is 8 in both save games. I ended up with this value by
 missing some optional act 3 conversations. Triggering act 4 by reporting
 Ernie will result in it being set to 11, which is the correct act 4 value,
 but doing so by getting the dagger will leave it at 8, leading to the
 lockup. The script patches causes the global to be set to 11 in both
 cases.

 This only affects version 1.0 floppy english. 1.1 floppy versions,
 including all localized versions, were fixed by Sierra.
