@S not working

Thank you for your report!
However, this report is Invalid.

Your game is modified with Optifine. Optifine is a very heavy game modification, and using it will automatically invalidate reports on the bug tracker.
If you can reproduce the issue in a vanilla game environment, please create a new ticket - this is a bug tracker for the game, and not a support website.

Any issues occurring from using Optifine need to be taken up with the developers of Optifine here, not Mojang Studios or the Bugtracker.
