If you crouch while shrinking and then cannot grow back to normal size, reload the last checkpoint. This combination is a confirmed gameplay bug that can block progression. Remaining small after that trigger is not a verified extra puzzle requirement, and there is no confirmed button sequence that restores normal size in the affected state.
The recovery is specific: return to the main menu, choose Change, select Start New Journey, and have the host manually re-select your last checkpoint. The host's checkpoint selection is the essential final step.
Identify the shrinking bug
The described trigger is crouching while shrinking. The resulting failure is that the player cannot return to normal size. Match both parts before applying this explanation to every section where you are small.
Being small by itself is not enough to identify the bug. If your character is still in an intended small-scale section and has not encountered the crouching trigger, the confirmed report does not establish that anything is broken.
Reload through the host
- Agree with your partner that you are going to reload the checkpoint.
- Return to the main menu.
- Open Change.
- Choose Start New Journey.
- Have the host manually select the last checkpoint.
- Continue from that selected point and check whether normal progression is restored.
Do not read the Start New Journey label as the whole procedure. The recovery instructions continue into manual checkpoint selection; stopping before that selection leaves out the part that identifies where you intend to resume.
This route returns you to a checkpoint rather than repairing the character in place. There is no verified promise about preserving every action performed after that point, so make the restart decision with your partner.
Avoid repeating the known trigger on the retry
When replaying the shrinking transition, avoid crouching during the shrink itself. That follows the described trigger and is a precaution, not a guarantee that every size-related issue is prevented.
If the character becomes stuck again, note whether crouching coincided with shrinking and whether the host selected the expected checkpoint. Those observations matter more than repeatedly trying unsupported jump, emote, or interaction combinations.
The known issue was awaiting a future patch in the available launch guidance. No verified patch number or permanent fix is established here. If checkpoint recovery does not restore progression, describe the trigger and failed recovery when reporting the problem rather than treating a guessed input combination as a solution.
