After the recent update, entering and exiting interiors seems to sometimes (not always, which is strange) prematurely end rain caused by Howling Conchs (RoG) and Dribble Pipes. I suspect this is due to the interior rain patches in the update. I'm unsure if this oddity extends to other player-induced rain as well, such as using the Telelocator.
Steps to Reproduce
Induce rain using a Howling Conch or Dribble Pipe, then enter and exit an interior.
This issue has been fixed in either a future version or updated in a previous version.
