Wyver dies in Ark?

I recently bought Ark for the ps4

Since then I play around with the blueprint spawn commands and whenever I die a waldwyver sparks die a short time later due to continuous damage, as long as I sit on the waldwyver after spawning it stays alive but when I descend (she is not tamed) she flies away and suffers harm again until death. The same thing happens even if I tame her, she suffers harm and dies. This varies depending on the life of the wyver, for example. Lv 1 is 2hit from the damage.

She gets the damage almost always in the middle just above the pelvis almost in the back and it looks like there's an invisible animal in the wyver in it that always causes the damage

Do you know what that is? Why does the Wyvern suffer damage? Is there anything in the DLC that the forest wyvern needs to survive?

Waldwyvern… Shoots with leaves or tendrils?

Does not help you… Sorry but do not know that.

On which map do you play there? This behavior is unknown to me, I would have to try it first, but it is necessary to know which DLC you are playing on…

Neither do I…
