Bug or I missed something?

I ran an auto duel with fusion deck against spirit lvl 33, start second. My AI activate thunder dragon effect; fuse one with dark hex-sealed substitute; then summon warrior Dai. It then attack with Dai first into Maharagi and tie. Then instead of attack a second time with Two head thunder dragon, it just end the turn, letting Maharagi survive and goes back to hand. I'm stump to why it did not kill Maharagi. I tried to check if dark hex-sealed prohibits that but did not see that. Did I miss something or this is a bug?

Have two counter gate's in my hand, my field is empty, enemy has 1 card with over 5000 attack it lays 1 of 2 trap cards down. Enemy summons 2 more monsters. had AI laid both down I would've survived... sadly I didn't.

somewhat AI won't destroy anything that AI 'think' it won't harm (in this case spirit monster will return to hand). same case happened to monster that revived by regretful rebirth, AI won't destroy because it think the monster will be just destroyed at next end phase (ignoring the potential of tribute or else).

AI has a very low functionality from what I find. It even avoids activating certain spells, like stop defense, or warrior returning alive.

the AI is just dumb and random
