List of Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey glitches

This is a list of glitches in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey.

Note: All names are conjectural unless otherwise specified.

Luigi Freak Out in Dimble Wood
If the player goes back through Dimble Wood once Mario is separated from Luigi, they eventually reach the room with the Wiggler. In this room, once Luigi touches the wall near the Wiggler, he starts freaking out and warping back and forth without any input from the player.

Luigi Stuck in Dimble Wood
In the same room, if the player climbs the ledge to the left, Luigi's behavior becomes more and more erratic. If they then leave the area via the loading zone there, they then get stuck in an infinite loop as Luigi warps between screens non stop. Saving here "bricks" the save file, forcing the player to delete the save file and start a brand new one to continue.
