Minecraft on BlueStacks and Mobile have this weird glitch that started for me a few days ago...
I cant craft... For example: if I have 4 wood planks, I could make a crafting table right? well here it won't let me, the same thing with crafting sticks, won't let me, and more!
ALSO
there is a glitch for items/blocks their pixels are out of place, such as at the end of an item or block, it would be darker or have an extra pixel.
here is a picture:

as you can see in the picture, you are not able to craft which is a big issue for people like me that are YouTubers, 
so please fix this as soon as possible... thank you for reading this.
