casino voided blackjack winnings because i used bonus funds on a restricted table

Hit a weird snag with a live dealer blackjack session last night. Played for a couple hours, got some lucky streaks, but woke up to an email saying all my winnings were voided. Turns out the table I played wasn’t eligible for bonus money, even though I thought it was. I double checked the terms and saw some vague lines about “certain games” being off-limits but nothing clearly spelled out. Support says it’s standard policy, but that feels sketchy - like how are you supposed to know in real time unless you cross-check every hand?

Anyone run into this before with live dealer games? If I’m consistently playing live tables, is there an easier way to avoid these screwups besides avoiding bonuses altogether? The fine print on these promos just seems to keep getting longer.
