The new "Can't buy a bucket" lines are basically the same as the "player x now has a double double" lines and are just commentary to add a little something to the match viewer. I know the "can't buy a bucket" one is buggy at the moment but it doesn't effect the actual game at all and should be fixed soon just like the double double line has been fixed.
Anyway, this is Bugs forum material so post it there next time please ;)
