Even if it will be an hotfix patch, then there is still a steam unpacking problem for many steam users. For me no single solution helps, so I have to wait to unpack downloaded i.e. 1GB for even 30mins or so.
I went offtopic a bit.
A small test server to find bugs before patch release and test builds, aswell as for testing translations before release as someone mentioned on Discord not so long time ago.
What could be bad with it?
