Codemasters is warning RF Online players not to use the Auction pager system for a little while, as it had to be disabled to prevent an in-game exploit.
We have identified the recent crashes as being due to an exploit involving the in game auction house Pager. As such we have deactivated the Pager temporarily during this emergency maintenance, until CCR can provide a permanent fix.
Players are advised not to use the Pager until further notice, doing so may cause the client to crash.
