There is a new First Look Update posted here. You can view the notes below:
First off, thanks to everyone who updated to the previous First Look patch, we were able to confirm that the texture bandwidth issue has been addressed. However, we also introduced a bug that causes some textures to never load after teleporting or changing regions. (Fortunately this should have a negligible effect on total bandwidth). We have fixed this here: First Look 18.104.22.168558.
Note: we are still working on the editing notecards from within objects and messages in postcards bugs and hope to have them fixed soon!
