3 years ago There was a similar problem mint (obj#140310 ooU4dzsX9TiAAko3u1qC21joq4iMHtP6KCupgkhvTcVa2PdxVh1). Looks like it happened in a block that got orphaned/re-orged, so it ended up correct in the end... https://tzstats.com/BLN4zkwj71ec83G9dXXWgZJwyDuULAVkQiVBunwFJ7aTqiVwTbZ relevant info:

There were simultaneous contract calls from 2 separate Hicetnunc users that ended up next to each other in block 1516913 in RPC positions 3/20/0 & 3/21/0. They were both mint_OBJKT calls to KT1Hkg5qeNhfwpKW4fXvq7HGZB9z2EnmCCA9.

Hicetnunc uses Taquito SDK to interact with users' wallets, with mainnet.smartpy.io as the RPC entrypoint.
Both users reported that they had apparently minted tokens that contain the metadata from the other user, so it looks like the sender wallet address parameter from one transaction was somehow associated with the other transaction's parameters (amount, metadata, royalties) & vice-versa.
Could this possibly this be a data contention/corruption issue within the RPC node?
This may also have happened to another user in the same block, and I'm trying to obtain further details. I've heard a few sporadic reports about this before, but haven't had the full details to be able to try to track down the issue.
As this is possibly an issue with the RPC node's tezos client, I've raised the above on tezos stackexchange to see if I can get further information; https://tezos.stackexchange.com/questions/3536/contract-call-sender-mix-up-what-happened
