Found a bug with River's route. After you talk with him and initiate the Route Start (for me), I went back to the park and his encounter happened again but this time it just asked him automatically to make the chainmail suit-to which he replied, then immediately after, game automatically asked for the other outfit-to which he replied, and then it said "nothing right now" which automatically closed the encounter. Again, automatically. Pretty sure the game took the player options as code? (not sure I don't make games/code)
