问题解决，感谢大佬！

粗略看了一下，475-478行

RUBY 代码复制

elsif @event_pop_id > 0
        hash = @event_pop_follower ? $game_player.followers : $game_map.events
        character = hash[@event_pop_id]
        self.y = character.screen_y + @oy - self.height + YSE::POP_MESSAGE::POSITION[:y_buffer]

elsif @event_pop_id > 0


        hash = @event_pop_follower ? $game_player.followers : $game_map.events


        character = hash[@event_pop_id]


        self.y = character.screen_y + @oy - self.height + YSE::POP_MESSAGE::POSITION[:y_buffer]

我觉得可能是$game_player.followers为空或者是事件数量不同导致了这个错误
试一下在478行前面加一行

RUBY 代码复制

return unless character

return unless character
