Many times I have seen biddings from other manager to get lost and not shown.
This most probably happens due to nordeus servers network issues.


When the round 1 ended if you were the only bidder you would have won.
As auction went to round 2 you should suspect that sthng went wrong and there was a bid that is not shown.
Keep that in mind for next time because I ve been there too

About the 0.1m increase of latest offer I have no clue and it seems weird.
But as there was a general sync issue in this auction I guess weird things can happen.

I would suggest to open a support ticket to Nordeus for both, at least to get your 2 tokens back.
I bumped into this kind of bug many times as well, fortunately without losing the auction
