A lot of my players seem to be getting told off that they're exceeding the group limit when using code locks (they're not). I know FP changed the way codelocks work this wipe, but I haven't dug into the code yet to work out what's going on. Just bringing it up.
I do use Automatic Auth as well so it's possible it's a combination of that as well, but it does give the group limits error from this plug-in at least.
