Phantom Blade Zero: Ticket Bug (Workarounds)

After killing the boss, you're supposed to get the Opera Ticket, right? My game crashed right after the fight. When I loaded back in, the game had saved my progress: the boss was dead, and I still had the weapon I got from him, but the Opera Ticket was missing from my inventory. Has anyone else experienced this bug? If so, how did you fix it? Is there any way to get the ticket back?

For the crash, try deleting projectpbz/saved/cache from the game folder, then recompile in-game. And for the ticket thing, just report it on the official site.
