betmgm casino game disconnected during bonus and replay never appeared.

so i was playing this slot, got into the bonus round and suddenly the game froze up and booted me out. usually when this happens i just reload and it picks up right where i left off, but this time there was nothing. no bonus, no replay option, just back to the base game with my balance unchanged. i checked history and there's not even a record of the bonus starting, just the spin that triggered it.

this ever happen to anyone else? is this a common glitch or should i be more worried? thinking about reaching out to support but not sure how much luck i'll have. any advice on how to approach this?
