R Mage

My suggested fix for the formula of horse breeding.

(pA+pB+pC)/3=Child Stat

(pA+pB)/2*R

pA=Parent A
pB=Parent B
R=Random # between 0.x and 1.x (to limit variability of child scores from parents, I suggest 10%[0.9 to 1.1] or 20%[0.8 to 1.2])

Lets go with Block Jump

Parent A = 3 Blocks
Parent B = 4 Blocks
R = 1.05

(pA+pB)/2*R

(3+4)/2*1.05

Child has Jump of 3.675

Elytra launch feature 😛

1. I placed two item frames in the same blockspace, but putting one on one side of a corner block, and another on the other

(Warning! crude drawing ahead)
------ [block]
b---] [_____]
l ---] — x —
o---]-x
c---]
k
consider this as the corner placement, and the two x's as item frames attached to the walls of the corner.

2. I had an ArmorStand occupy the blockspace

3. I ran an /execute command to teleport all ItemFrames in the same blockspace as that ArmorStand, to another corner with another ArmorStand

4. the ItemFrames teleported but like so

---] [_____]
---] — x —
---]
---]

With the second item frame displaying inside the first item frame.

5. I broke the block that was supporting the item frame, it persisted.

6. I used a piston to push the blockspace, it persisted.

7. I attempted to place a block in the blockspace, this was not allowed as an entity was considered to be there.

8. I relogged to ensure it wasn't a graphical glitch, and repeated steps 5-7, the Item Frame persisted

9. I used the /kill command targeting ItemFrames, the ItemFrame was removed.

What did I think would happen?
Not sure, present the particle effect in a different way. .. or atleast generate an error saying it was impossible.

What actually happened?
The server crashed.

How to trigger the bug?
Put -1 in the speed field of the particle command
