It seems a new option that was added to the nwnplayer.ini configuration file by patch 1.64 of Neverwinter Nights could cause, if enabled, all text in Cleave's view/text window to become fubar'ed.
The option is called ClientEntireChatWindowLogging and if set to '1' will cause NWN to log *all* messages in the message window to the chat log file. Version 1.1 of Cleave will now simply skip the extra messages.
