I am currently unable to see experiecnce while it is traveling on bubble column and along water streams. This issue started recently during the 1.16.220 verison release.  It has been reported by other memeber on the realm. The player is still able to receive experience as it is still travel through bubble column and water streams. This bug make it difficult to see how and why some of the experience orb are getting stuck along there way to the player.  When I back out of the game and re-enter the realm the experience orbs appear but any orb's that travel alot the stream or bubble column are not visible to the player.
