The author of SG2D, Adrian, has a "JOKE" that he created within SG2D that when used on April 1st, gives the impression that your PC is being destroyed. IT IS NOT!
This PRANK has been present for years!
Its his way of having fun with his user community since this a common behavior in many community where its 'acceptable ( )' for pranks to be played. So, if you run your SG2D on April 1st, BE prepared for a scare from his way of being funny..
If you are unhappy with this kind of playful banter, let him know on his GITHUB for SG2D.
Enjoy
