Auction.sol#L248-L254
If the first auction is paused and unpaused in a protocol deployed with no founder fees, the highest bid (as well as the first NFT), will get stuck in the protocol with no ability to retrieve either of them.
In a protocol with founder ownership percentage set to 0, the first tokenId put to auction is #0.
If the first auction in such a protocol is paused and unpaused, the check for if (auction.tokenId == 0) will pass and _createAuction() will automatically be called, minting the next token and starting a new auction based on token #1.
The result is that highestBid and highestBidder are reset, the first auction is never settled, and the highest bid (as well as NFT #0) will remain stuck in the platform.
The following test confirms this finding:
Manual Review, Foundry
Remove the block in unpause() that transfers ownership and creates an auction if auction.tokenId == 0 and trigger those actions manually in the deployment flow.
