After starting a new singleplayer game, I've found this in my logfile:

40218.597 Script @__themightygugi_longreach__/event.lua:185: Error in event on_player_joined_game: "LuaPlayer doesn't contain key force_item_pickup_distance_bonus.".

In function set_join_options(), you're trying to access the following properties:

game.players[event.player_index].force_item_pickup_distance_bonus
game.players[event.player_index].force_loot_pickup_distance_bonus

I suppose this may have worked 3 years ago, but nowadays LuaPlayer::force_item_pickup_distance_bonus and LuaPlayer::force_loot_pickup_distance_bonus don't exist anymore. Instead, we have LuaForce::character_item_pickup_distance_bonus and LuaForce::character_loot_pickup_distance_bonus, so you should use

game.players[event.player_index].force.character_item_pickup_distance_bonus
game.players[event.player_index].force.character_loot_pickup_distance_bonus

instead.
