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'll eventually reach the room with the Wiggler. In this room, once Luigi touches the wall near the Wiggler, he'll start 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 behaviour will become more and more erratic. If they then leave the area via the loading zone there, they'll then get stuck in an infinite loop as Luigi warps between screens non stop. Saving here will 'brick' the save file and cause the player to have to restart to continue.
