In the Marauder rank 30 quest "Two Man Crew" you are required at one point to enter an instance where you need to open some chests without creating noise.

There are supposed to be green dots on the minimap that indicate which parts of the instance will create noise when you walk over them, unfortunately these never appear for me (I only realized they exist after checking a video of the quest being completed on youtube).

For some other reason opening any chest at all causes a noise, once 4 noises are caused you are kicked out of the instance which basically makes the quest impossible to complete.

I was hoping for a fix in 1.19a but it didn't happen.
