It is a good idea to install Steam updates manually so you will not be updated and not be able to join the server which will typically have to wait up to several hours after a patch before it can be updated.

The server is dependent on the OXIDE devs to update their mod and they don't even know to update it until a steam patch drops so it understandably takes them a few hours to get it done following a Steam patch and only then do I go in and apply both patch to the server at the same time.

All this can take a hour, 2 hours, 4, 8, maybe even 12 hours if the OXIDE guys have problems. That's either 12 hours of you not being able to join the server or 12 hours of you playing care free depending on if you turn auto update on or off ;)
