So I received my beta access 2 days ago and I noticed bugs and issues with game, I read steam forum but is says we can only report it on VIP form but I have no access to it so how can I contribute to bug reports?
You should be able to get access to it by unlogging then logging again.
By memory, just leave the forum part of the webside by clicking on anything on the upper bar, up your screen. Unlog and log again there.
When coming back to the forum, you should be able to access the WIP subforum.
