I found out the hard way… It seems Steam pushed the UK release to Midnight GMT. This means that my game still said ‘Pre-load’ and wouldn’t let me play when I was certain I could. With friends in Europe who were playing I assumed this was me bugging.
I sadly proceeded to follow the troubleshooting… and uninstalled to start re-install. Now i’m kinda annoyed as I could play in 3 minutes, now have to wait 2 hours.
Just wanted to warn people.
