[GAMEPLAY] Dragon permanently stuck outside its pit, always on reset.

I have no idea what caused it, but after the enemy team pulled dragon outside of its pit, it sat down and got stuck there.

It was permanently on "reset" - regenerating health as though it was out of combat. It would start its flying combat animation, but would not attack. Eventually we killed it in spite of the regen, but it took ages. Afterward, it spawned normally and the bug did not reoccur(Though I haven't tried to recreate it since.)
