Am i the only one having issues with auto battle (the green one, not AAB)

Sometimes when i activate it, it just freezes for a few seconds, and then instantly does way more turns than it should. It's like 10 turns in 10 seconds (freezing time included)
I've failed an AQ and a rag because of this

I also have the "wait for last turn to finish" thingy constantly since last patch.
