Full test code to showcase the desctructable animation delay that affects height immediately after creation:

print(x,y,z)
end

This commit has the full testing code for the "delayed destructable height" bbe9760
Very much like in #148 , the created destructables delay their "final" position by one tick because it needs for the animation to play.
This is the map that does everything automatically and prints that Z results console. I've asked for people to run it in HD to compare against my SD results. I just want to confirm this for myself. Early on this was a major desync reason on Reforged release, actual model animations affected the surface elevation (if walkable destructable) and THAT caused different values between HD and SD players. I have no idea how they solved it exactly, but they did take agree on one value as far as I understand.
because this SD model still has different animation heights when compared to HD. And then what if you trigger DIFFERENT animation variations, one that exists in HD but not in SD? I guess that's still a desync even today??
Feel free to review, but before merging please wait until someone has confirmed the test map output on HD.
