Help with A sudden error

I don't know why whenever i start my game this error comes up
Exception: ArgumentError
Message: comparison of String with 0 failed
Game_Event_:161:in `<'
Game_Event_:161:in `nf_particles_game_map_refresh'
Game_Event_:148:in `each'
Game_Event_:148:in `nf_particles_game_map_refresh'

and then my game will stop to run any ideas?

P.S I'm sorry i ask alot of questions but i tried everything possible like deleting my save replacing the scripts but it still does'nt work

If this is on Player House, try to remove the condition for the bottom right NPC downstairs (the one with all the messages).

If isn't, try to remove from Game Variables (in debug) string values (some string may have numbers). Just confirm the value that strings will be turned to 0.
