there are no null checks so if an object is null it will throw a NullReferenceException

you need to add null checks for ServerUsers.User serverUser and BaseBlayer player objects, and also before you call AddUserPageInfoLabels. there might be more needed as well

this actually throws out an error message for me when clicking a players name and the player is dead or no longer exists on the server..

not sure if it is the same for the OP.  Maybe it could display a message stating that the player info is unable to be displayed due to the player no longer existing or something?

running v1.6.02.

there was additional mods on the last update, which i took a look at.
it's not listed in the  revisions..... but  now it dicks about with a lot of un-needed string generation, where as before it was longs... with a conversion to a string when absolutly needed... (specifically related to missing players/missing corpses).
When  a player is in a game and goes into off line mode, then the body dissapears/destroyed..... there is a lot of boundry cases, since the player avatar only "comes back" when they rejoin. cleanup in rust is quite poor in these situations...

It becomes an issue when plugins start making assuptions on game state related to players in this state, like Teliporting & such.....

Ultimatly I decided to give the update a miss

Missing null checks at lines 1411 1431 1454 1521 and inside the AddUserPageInfoLabels method are the cause of your exceptions

It would be better to store the player information such as displayName, ServerPosition, NetworkRotation etc in the Cui object when it's created on line 211. This way if the player is null later then you can use the last known information instead of displaying nothing.

so for example

at line 201:

			public string _networkRotation;
			public string networkRotation
			{
				get
				{
					if (FPlayer == null)
					{
						return _networkRotation;
					}
					
					return FPlayer.GetNetworkRotation().ToString();
				}
			}​

and _networkRotation = aPlayer.GetNetworkRotation().ToString(); when the Cui object is created

then line 1301 could replace `aPlayer.GetNetworkRotation()` with `aUIObj.networkRotation`

etc
