I tried it and it still works. If your having trouble the trick is to immediately as soon as possible throw the nade down. I noticed if i don't blow up and hit the ground before it ends the game I get no exp. Crashs a bit though.
I will look into it. The pointers are not the best ones btw but thats why i added multiple ones. If it still doesn't work then it's a problem with your PC and probably all my pointers would not work. I tested it again now and it's still working perfect for me so not outdated.
