Pausing + visual effects in certain locations

Bug Report ID: #4,011,134,308

When pausing the game in a location such as "The Caverns", where there are purple/black visual effects swooping across the screen, these visual effects will accumulate over the duration that the game is paused, resulting in a large amount of them being on screen when you unpause, and eventually disappearing after their duration. Image attached after 2 minutes or so of pausing, and after around 20 min of pausing (when I first noticed the issue) it was significantly more.
