crypto casino says my bonus was cancelled because i tipped rain before wagering cleared

I just had this weird thing happen where I was playing on a crypto casino, working through a deposit bonus, and my balance seemed fine. Out of habit I threw a few satoshis in the rain since the chat was popping off. Few spins later, I get an email saying my bonus is void because I “transferred funds” before meeting wager requirements. I checked the T&C and there’s this vague line about not moving funds during the bonus period, but I didn’t think tipping in chat counted. I usually tip low-rollers when I’m up a bit, so this caught me off guard.

Does anyone else run into this, or is it just another way they find to deny bonuses? I know bonuses come with a lot of strings, but I hadn’t seen chat tipping punished like this before. Not sure if it’s worth chasing up with support or if they just dig in their heels and quote rules. Feels like a minor technicality.
