Me and my brother where annoyed of crossbows
Because it can cause to destroy blocks (when they are 12 blocks near in creative mode) at the same time you shoot an arrow with the crossbow
Even split controls can cause this bug
And shooting with fireworks and potions arrows will get the same problem in creative mode
That's why we have to hold on the top screen of our phone (when the crossbow was ready/ has arrow) or go far away from blocks just to shoot without destroying any blocks in creative mode
In survival/adventure mode, the crossbow is just fine
So, maybe you should make crossbow similar to bow in creative mode, like it won't destroy blocks after aiming/shoot
By the way, my phone was Android - Flare S4 and brothers is Flare X
And it's from Cherry Mobile

Confirmed. Apparently its not random. It destroys the block the the player presses to shoot. Personally, I think it should shoot by tapping the screen instead of press and hold to shoot.
