Potentially. However, a lot is messed up in this instance.
For example, we are mainly on the (sub-)domain xen.bighugegames.com, but some links like the home button at the bottom right lead to forums.bighugegames.com, so that, among other things, the login is lost. That's what bhg messed up because they don't seem to get along with their domains.
deprecation error is displayed in the google chrome console and 'cross origin read blocked' issues; indicates an old outdated version. This raises the question of whether bhg has forgotten updates or whether the provider is not up to date.
Another example: If you ignore people, then all threads disappear completely where the ignored person last commented. That's a pretty stupid solution instead of just hiding the ignored person. This is probably not bhg's responsibility, but a flaw in the forum software. My workaround is a small script to take out the corresponding 'div' or 'article' html elements.
