Raddus not calling reinforcements on auto

Just wanted to see if anyone else is having this issue or if it's just an issue with my local client.

Final tier of the Raddus event, ran it on auto, Raddus never called a reinforcement until it used its ultimate, and then called one.

I didn't try again because it would cost 999 Crystals. :/

Edit: Forgot to add that while on auto it only used its first ability. No, it wasn't on auto basic only either.
