Donovan Watteau 500a54a559 Revert "AGOS: SIMON2: Fix pirate dialogue freeze"
This change introduced several character animation regressions in the
game, which may seem as a worse experience than the original issue with
the pirate dialogue, for most end users (Trac#13997).

This reverts commit eb851041ed.
