If another player gains control of the tokens created this way, the ability that causes you to sacrifice them will still trigger. However, any tokens you no longer control can't be sacrificed and will remain on the battlefield.

If, for any reason, an Aura token that would be created this way can't be attached to Stangg Twin, that token isn't created. If an Equipment token that can't be attached to Stangg Twin would be created, that token enters the battlefield unattached.

If a replacement effect causes the created tokens to have different characteristics or causes additional tokens to be created this way, those tokens will still be sacrificed at the beginning of the next end step.
