I'd guess there is an unterminated message in a sys_vgui call-- i.e., one with a "\\\n", possibly in a loop-- and a matching sys_gui or vgui call with a terminating "\n" at the end. If you put a message to the gui between the two you'll probably screw up that command. If you insert a message with a linebreak in it, then tcl will take the word immediately following the linebreak-- like a "1000" or a "1"-- as a command. Those aren't tcl commands, so it complains.</span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif; background-color:
