Happening consistently in Syrcus Tower for me as well, now. Every time the purple gate goes up, it seems. Hasn't happened in any other instance, however.

It would be really nice if mods would actually respond with something other than a canned answer with a list of fixes that haven't worked for a single person so far. It's getting really frustrating that I can't even play a game or use a fantasia that I spent real money on because of an issue outside of my control.
