roulette bonus funds blocked after i used racetrack layout

So I was playing online, trying out the racetrack layout for the first time after watching a couple streams on how folks mix sectors with bonus cash. After a few spins, I suddenly couldn’t access my bonus funds - just straight-up locked out. Support gave me the usual copy-paste about “irregular play patterns” but they won’t actually explain what triggered it. I didn’t max bet or try to cover 90 percent of the table, just mixing neighbors bets and a couple of straight-ups, not even close to abusing the promo.

I’m curious if anyone else’s had bonus restrictions kick in just because of using the racetrack or if this is a bigger trend. Makes the whole promo system feel rigged whenever there’s the slightest excitement and boom, account flagged.
