Dialog instances occassionally cannot be interacted with on touchscreen devices

Reproduction Steps

  1. Create a part or NPC
  2. Parent a Dialog inside of that part or the NPC’s head
  3. Put a nest of DialogChoices within the Dialog for good measure
  4. Observe, on occasion, the Dialog bubble cannot be tapped or engaged with on a touchscreen device

Expected Behavior
Touchscreen devices can use the dialog UI + bubbles.

Actual Behavior
Touchscreen devices are occasionally unable to interact with the dialog bubbles. Tap as many times as you would like, nothing will happen. If dialog is a core gameplay mechanic, that player cannot progress.

Hello! Thanks for the report. Filed an internal ticket.


This is still an issue as of December 2022.

I get these reports like this somewhat frequently:

Hi @cloakedyoshi, thanks for submitting this bug report!

I was wondering if you have some tips on how to reproduce this bug? Is there a specific placefile or mobile device where this issue occurs more often?

I tried to repro with this place, and the dialog worked correctly on an iPhone 12 and Samsung Galaxy S21.

Unfortunately I do not. It seems somewhat random.

If it helps, I always suspected this bug and error were related to it:
