How often are trial dungeons bugged?

[Richard Richard Johnson]

So far 75% of the trial dungeons I've gone to are bugged with a puzzle that requires you to enter through another door to finish it without any way of getting there or have high walls that make shooting torches on impossible. Am I just unlucky or is that about the rate that trial dungeons are impossible to get through?

I haven't had any issues. Did you have a screenshot?

In my my cases I was always able to use a drone to get around the things I couldn't directly shoot, shoot through the red/blue walls, or throw something over/through the wall.

Screenshots do wonders for confirming bugs or user error.

You always have to carry a toy of legend that you can throw to hit switches, light bulbs, torches or else. You can either keep the bow or the vinyl-frisbee. Keep in mind that according to the era &/or toy dungeons, one of these two may not be enable to get from the start (as they may be a reward at the end of a toy dungeon).
Knowing that, you can light a torch close, and hit from behind it to your target. The toy should be in fire. Some walls are short or have cracks that let some toys pass through (especially for vinyl-frisbee).
