I'm having same issue. Been happening from yesterday. Can't see how many items i have in my inventory and multiple items in back as just displays pic of item and not number. Also items keep going invisible in inventory and bank. Any news on a fix for this as makes it hard to do archeology when you don't know how much you have or can't see stuff.
Afraid I don't know of any estimated date for the fix, but rest assured Jagex are aware of this issue.
