The Art Assest Library.

I would get down on my knees and kiss the feet of anyone who can help me delete my massive library. Every time I click select all and click delete selected it simply does not work. A popup says that the team is simply just not working on the asset library and sometimes it will just not work. Seriously....

If you are trying to bulk delete stuff, go into your game and click on the asset tab>double click on any image in the recent addition section to open your art library. Select up to about 20 or so assets then try deleting them. Some people can do more and some can only do a few less but 20 seems to be the average. It still takes awhile but it does save a slight amount of time.
