Edit: Ignore this comment. I didn't even notice this issue was patched, but the patch was uploaded separately.
Edit 2: So uh, i installed the patch, and now not only do i get the infinite crystal the other guy was talking about, but i also can't enter the gym now
Edit 3: Passing a day allowed me access to the gym again
