No, I selected Darkcoin as autoexchange coin (also had Bitcoin a short while), never any others.
We will investigate on it.
Sorry if there were some bug.
Oh, sorry we found a little bug which was caused by PHP precision limit.
A small amount of coin like 0.000000000000028, which is even not able to calculate from coin network (Satoshi is 0.00000001) was left and made things messy.
Since adding all the coins to transfer was not enough to match pre-calculated amount, server tried to send one more time and it was piled up with other miner's auto exchange coin transfer.
You don't have loss only pool does.
You can also verify from your givecoin transaction that same amount "191.14491952" was sent twice and logged as id 1731250 and 1731251.
Well, this PHP precision limit buggy situation did not happen frequently so pool's loss was very small too.
This is why we didn't notice this kind of bug. Very low loss and low frequency.
Just take this coin as a bonus. Sorry and thank you for you report.
