Underwater impulse sound on land..

Sorry for bumping an old post, but I tested something similar to this last night and remembered someone had posted about it.

All sounds on the "drowned" player will continue to play echo sounds as if underwater for the entire remaining session. However, I found it's only persistent this way if HD mode is turned on beforehand. Here were my steps to reproduce:

1. Enter a project with two characters.
2. Turn HD mode on.
3. Leave one in play mode, the other in edit mode
4. With the character in edit mode, spawn a water plane underneath the playing character
5. Drag the water plane above the playing character
6. Delete the water plane
~~~ For a few seconds, the playing character will be swimming in midair - if they start falling they'll start falling as if they're swimming ~~~
7. Have the playing character pick up a weapon that makes noise or use a sound emitter
-> You'll find that the playing character will be hearing noise echoes as if they're underwater, but are not. Even entering edit mode and returning to play mode doesn't resolve the sound problems. I also tried spawning a new water plane under the playing character, but it persisted. Even going to a much higher height than where the original water plane existed didn't fix it. Only refreshing will.
