Figured it out, config was messed up.  Tried deleting this, and can't figure out where.

I've updated, deleted all files, updated oxide, and still get this - randomly. Suggestions?

Find these (search for unHostileTime) and switch them to this:

string pt = ((int)Math.Abs(player.State.unHostileTimestamp - Time.realtimeSinceStartup) / 60).ToString();

var pc = player as BasePlayer;
string pt = ((int)Math.Abs(pc.State.unHostileTimestamp - Time.realtimeSinceStartup) / 60).ToString();

that will not fix this error. the issue is

!Clans should be Clans == null

and

!Friends should be Friends == null

Periodically spam the console. What is the problem?

are you not using Friends plugin?

Yes I use

idk then. it is already null checked

nivex

idk then. it is already null checked

It sounds like one of the IDs being passed to it is null.

I thought so too, but if that were the case then it would throw the error at IsInSameClan instead of AreFriends, since it is called first

Or does the other plugin check for that?
