Sorry if this has been covered already, but I couldn't find anything on it.
The issue here is with adding Vessel (PC) to any section in the games list. I have added Vessel to the list of games I'm following, so simply check my profile to see the issue. If you check the last three games added to my following list, you'll notice that the title for Vessel is missing and the release date is blank. If you look to the left side of my profile, it should show you that I'm currently following 40 games. Now, if you go into the I'm Following section to see all the games that I'm following, you'll notice that Vessel is not listed and that on the left side, it is showing that I'm now following 39 games.
At this time, this is the only game I've come across with this issue. Minor problem, but figured I had better mention something.
