disconnecting: RPC Error in OnRespawnInformation: Object reference not set to an instance of an object.

Looks like something outside of the scope of PA/uMod.
As for the "BuildUserPage" issue, this is likely related to what's been reported a couple of times before, the username containing some oddball characters.

so that the error does not occur anymore, the uipanel offline players would have to ask the players again when clicking on the button

it is so that I can see players who are no longer on the server that they have killed themselves and have left the server.
when i have this error with a player i reload the plugin and the player is no longer in the list
so therefore the list is not up-to-date

player.identities <- I don't use this, perhaps oxide/umod uses this somewhere. Might be worth checking.

Thanks for the merge, Wulf.
Tried everything I cared for to try. People are not providing any kind of log file and not trying test builds so I said "Fuck it" :)

PS: The mod has it's own log file, enable the debug flag by editing the mod, reload it, make it go boom, share the mod's log with me so I can actually try to debug things without flying blind.

I think I caught a hacker using the plugin  just after loaded..........

Can you also explain why just after adding you plugin
a user  "magically" appeared into my server at exactly the SAME location as the admin...

But what he did not know was I have a  home grown  "Anti hack"
This user shows up as "NUMUNN" in the  admin console for the plugin
and shows up in battle metrics as "power"

BUT..... lists as.....

taking a quick look at the code.... there is no reason for players to "appear" from nowhere ,so I guess it was an "accident" he got caught...

 I think what is happening....
is that  "somehow" we have a group of players spoofing steamID's  and "being"  multiple other players, including "admin"

when the plugin's run...... the  steam ID's  & server data structures don't correspond so the plugins are throwing errors due to the player data being "null"
then people are saying... "crap plugins", when in reality we seem to have a fairly efficient "hacker detector",  clearly we should be Exception trapping this call & using it to detect spoofed players.. whilst we have a way to detect them....

I've sent a set of logs/player data & screen snapshots with these accounts to steam & RUST.
This guy slipped up...... I caught him in the act...
