casino removed a slot from bonus list while i was still wagering on it

Has anyone had this happen before? I was working through a bonus and using my usual slot game, since it was definitely listed for bonus play when I started. About halfway into my wagering, I went to spin again and suddenly got a notice the game’s not eligible anymore. It didn’t even show up on the bonus games list after that. Tried reaching out to support but all I got was a canned answer about game eligibility updates.

Honestly, this messes with my usual discipline. I try to keep stable routines with slot selection so I don't trip up the bonus rules. Did you ever have a casino pull a game mid-wager like this, and did they do anything for you?
