^^ That is an Imgur link where I have photos from the replays of my game, showing the mountain dragon spawning after 2 ocean dragons had spawned.

This bug really screwed the enemy team, I go over the bug fully in the Imgur link!! I also posted this on Reddit bug post, but I really hope it gets looked at, it seems pretty obscure bug though no clue how it happened or if it will even happen again
