Hi there!
So there has been something weird going on with my blocks-
1. Whenever I try to drag a block of code from one sprite (1) to another(2), the block of code dosent appear in the (2) sprite.
2. The glide block is not working.

Thats all, I will tell you if there is anything else wrong with the system, and I will tell you if it works now.
