now with a case from a Greek forum member, I learned this too

Every time you increase the offer for a player, nordeus keeps a token.
{Support answer :You're missing 3 tokens because you changed your offers 3 times - every time you change your offer this costs you 1 token that you don't receive back if the offer gets rejected.}

If you do that 3 times and the other manager reject this, time has finished and you got back the token, it's 3 token less

Of course I want to add it in the first thread.
No deal, no missing tokens.
