I do think there was another issue here as well. Let me explain further:
This is the 1st screenshot, showing that the deposit was received - even though the block hasn't been mined yet.

Shortly after, still without a block, it was changed to this:

I have no idea where the amount came from, and as you can see the total amount in the same ID transaction was changed from 3 mBTC to 0.3 mBTC (site minimum), asking me to deposit the difference up to a new amount (lower) and not the originally requested one.
I think the case needs further investigation by the team but then again - both my swaps ended successfully. It was just a bit confusing.
