crypto casino marked my doge deposit as underpaid after network fee moved

Was just curious if anyone else has had this weird thing happen. Sent over a Doge deposit, copied the address like usual, but right after I sent it the network fee shifted. The casino's wallet must have seen less than the expected amount and flagged my deposit as underpaid, even though the transaction ID matches and the difference is literally the miner fee. Support’s acting like it’s my fault for not covering that swing. Never seen a fee jump like that right after hitting send.

Feels sketchy to me, and now my funds are in limbo. I get that casinos automate a lot of this stuff but shouldn’t they take network fees into account before marking things as “underpaid”? Can’t be the only one who’s run into a problem like this - do you guys just always overpay a little to avoid getting stuck, or is there something else I’m missing?
