this is
"View offset" or "Look function" (if you not play with mouse it may be set at mouse x thats why its look where mouse arrow is) in Options > View
Maybe beacuse that commend exist in exe. DCON should check version of file but it does not check it.
Simple solution: redownload DCON 6R and replace old files with new ones.
I just tryed to use teleport on normal server and i got "› Draggo : OOS - CAR"
For your information /modified=no is related only to CPW errors not OOS.
From where you downloaded DCON?
(if you get it from that site you have in your profile, you got modified version, on this version tweaks will be always works)
