share a PC, there are 2 steam accounts and separate copies of Dayz attached to each.
The usual issue of logging in to find housemates character and IGN, also the IGN does not correct when we join a server.
More worryingly it seems our GUID's are getting confused by Steam and/or Dayz.
example
I am whitelisted to several private shards, my friend is not, sometimes I am unable to join those servers (I get the 'Not whitelisted' message) and sometimes my friend, using his own steam/dayz accounts can join the whitelised servers despite not being whitelisted.
On other occasions neither of us can join the whitelisted server, it appears to be somewhat random however we noticed that if my friend plays Dayz multiple times without me playing inbetween then I am always unable to join the whitelisted server.
This suggests that our GUID's are being switched between accounts from time to time along with character and IGN's.
