I was playing a ranked game in MTGA. The adversary has a Scute Swarm that was mutated by Auspicious Starrix. I used Lullmage's Domination to take control over the creature. Then in the other turn, the player mutates another Auspicious Sarrix with Migratory Mithorn, and the abillity of both creatures in mutation was trigged, than exiled a creature and entered in battle field and a land as so. But when the land enters, it triggered the landfall from Scute Swarm, as if it was in his control, but it was in my control, and that trigged the abblity a million times, and I lost the game. If you can revise this, I would be very glad, or if you can explain me better other things on this play I've missed, I'll be very glad. Thanks :)

Game hangs when Auspicious Starrix is played for its mutate ability, and opponent concedes during the resolution of Auspicious Starrix's ability. It has happened a few times, always with Auspicious Starrix, always when it is payed for mutate, and always when the opponent concedes while the new cards that auspicious starrix introduces via its ability.
There is no options button, the game freezes, and I need to exit the game using windows key. I have attached a log file, but it wont be of much use, since it was made after re-entering the game after the fact. I didnt think of making a screenshot..

I had Brash Taunter in play. I played Kroxa, Titan of Death's Hunger from my hand, and entered full control . With the Titan triggers on the stack, I tried to to have Taunter fight Kroxa, then the game prompted me to verify that I was sure I wanted to target my own creature.

At that point the screen wouldn't respond to yes or no, but it would let me view the battlefield. Since I couldn't say yes or no to leave the screen, I lost all of my timeouts while it was stuck.

When the triggers were all on the stack, my selection had changed to a different creature; the trigger on the stack wasn't targeting Kroxa for some reason. It was my last turn alive, and it could've been the difference between a win and a loss. Either way, it was a bug, even if I had managed to win.

Incorrect Rules Interaction. Hoping this is the spot to write and post it..
This is the first situation…
This is the situation I was in when I believe the rules might not be correct.
1st main phase: It was around 6 turns in I just casted some spells.
Attack phase now: I have my dogs and pack leader attack. Pack leader makes all dogs indestructible for that turn..

2nd main phase : This is were I cast "realm cloaked giant". I casted this in the sorcery spell which states "Destroy all non-giant creatures". So is that a specific rules that destroys all creatures except giants? Also what about creatures that a indestructible?.

This is the second situation…
Now the second battle with a different person, I had my dogs out with "Selfish savior".
It was the opponents turn and now his 1st main phase he cast "massacure wurm" which gives -2/-2 to all creatures. As he cast it and waiting for my response and I activate my "Selfish savior" ability and protect one of my dogs until the end of turn.. Now before the attack phase even starts all my dogs had -2/-2 on it or was dead which I can see that… Yet the dog I protected was dead even though "selfish savior" protected that one dog…
Now I can see "Selfish savior" says destroy or not to destroy and "massacre wurm" gives -2/-2.
So now I need to get some clarification on the rules in this matter….
Thank you…
