[2020] Second time jagex has put off a patch now....

Hi everyone - we are working on the bug above - it has taken us a little longer than hoped to fix though, I'm afraid.

I did gather this though from one of our Art team that has been fixed - it's a smaller fix that may impact some who were seeing the issue:

Fixed issue where per map square cubemaps blended incorrectly resulting in a 1 to 2 second appearance of high reflection on some assets and characters. This issue has been resolved and reflection transitions between map squares appears correct.
