Comment (by antoniou79):

 I am seeing the same thing (crash with Seg fault) when loading from your
 saved game. I am testing with the Windows ScummVM 2.9.0 release version
 and also a local msys/mingw64 build from recent master HEAD for 2.10.0git
 on mine (I am typically building in release mode, so with enable-release
 and disable-debug, so I haven't tested in debug builds).

 This is the output for gdb in msys2/mingw64

 Also I should add that on my original playthrough of the game, a few
 months ago now, I also did have the issue of getting stuck when trying to
 get on the forklift from the right side of the forklift (left of the
 screen as the player looks at it) but that was "resolved" by going from
 the other side. Still, that is also probably something to investigate for
 fixing.
