scummvm/engines/lastexpress/entities/yasmin.cpp
Evgeny Grechnikov f771fa40ad LASTEXPRESS: multiple fixes in NPC logic 
Checked the logic against the original game
(to be precise, DOS English version from GOG, although I think
AI logic has no significant differences with other versions).
Fixed a *lot* of errors with varying visibility for the user.

Also, save+exit+load sometimes resulted in memory corruption like
((EntityParametersSSII*)(new EntityParametersIIII))->param8 = 0;
load operation did not restore the correct type of NPC logic context,
the default one was used (which also has the smallest sizeof).
Should be fixed now. Save+load is still unusable because it locks
everybody waiting for kActionEndSound (the sound state is not restored),
but, at least, it should not corrupt the memory. Hopefully.
