The codefix for options not sticking shows to remove this line
ch->act = multimeb( PLR_BLANK, PLR_COMBINE, PLR_PROMPT, -1 );
This also causes new players to not have a prompt, so they never get the Type HELP START prompt or whatever that is. They have to type config +prompt which they may not know if they are new to afk.
I'm not even sure what the best solution is in this case, but I fixed it by putting
SET_PLR_FLAG( ch, PLR_PROMPT );
reset_colors( ch );
