Hi! This weekend update features a new version of the connection plugin we use for online sessions.
It should help with some of the issues that were introduced in a previous patch, as well as with some of the older ones.
In short, if everything works properly, online games should work for pretty much everybody.
Be warned, we haven't tested it much (it's a weekend after all!), so some new bugs may arise. We'll be on the lookout and revert the update if it's serious enough.
