I recently started playing Gehn Shard, and invites don't seem to be working.
A buddy of mine can receive the invitation, but when they're at the Nexus, nothing shows up for them under Private Link.
We can play together via book sharing, but if they get booted from the age we need to go through the whole book sharing process again to link back up.
This all works fine with Uru Live Again, but I'd much rather be playing on Gehn Shard.
