Ran into this, don't know if it's really a bug. (Can be like this in real life.)

Might add something to screenshot already posted.

Same problem here. What seems to help for me (workaround) is to drag the 'gear' into the vicinity and back in.

Got the same issue even on '0.42.116181' version.

This has happened to me twice by accident -> it really ruins the game if this become well known. (Up Vote!)

@Dev/mod

Is it a option to remove the password/ kick options for server admins for now.

Password on the server:

It shouldn't be possible to set a password on the server if it's not allowed by the rules at this time**;
I just did a count just before posting, 13 servers with a password on it and 9 servers with 'literally' the words join=kick in the server name. (even more server if u count in o=0 I=! Etc.) 21 servers, that's only a fraction of the servers listed, so this is a minor 'issue' I reckon, but still annoys me like hell every time.

I don't mind privet server, I even support it, if it is for setting up/ protecting a community, and to be honest they pay good money for hosting the server in the end.
But if there are only <5 (did use ~number before but that did give me a strange link like this: ~5) people connect to a server with a password on it (99,9% of them) it's for gearing up and getting a advantage over the 'regular' people playing.

**Just remove the password option until it's sorted to exclude those server characters from the 'main' hive:

Kick option for server admin:

It's being abused if u asked me (no one is asking me :) ) I got kicked from several servers and since it only allowed to use a certain circumstances. (http://dayzgame.com/downloads/Server_Hosting_Rules_Public.pdf) It's only possible to figure out who your dealing with if the person is unconscious or death (checking pulse), and the can only bother u when you are in the 'area' and the if the 'abuser' is death or unconscious (< Kill it) the change of running into them again is slim. (Make it a option to report people that abuse, and investigate/ auto temp ban when a certain ammount of individeal reports a player)
