Sponsors problem

I've just ran out of contract with my 4 sponsors and went on to re-negotiate with them.
I've signed straight away with my main one, but the rest refused. I went on to get a newer ones, which I haven't talked with and they've also refused signing with me. So right now I'm only left with one sponsor only and no one else willing to sign with me. I must wait for another race before I can negotiate again with them. Kinda odd stuff.

Last season I was banking in over 5 millions from sponsors only, so I've banked up a bit of spare change for rainy days, but some of the sponsors declined signing in with me for even as low as 700k, which I find rather ridicilous.

Can someone explain to me how negotiations work, if that's not a bug ? Please ?
Thanks in advance !

lolololololol.... Sucks to be you. hahahhaahah...

I think they realised they was sponsoring you, so they pulled out of it. :D :D :D

 Use auto-sign, it will sign contracts even if you have no bids left.

And I would aim to renew future contracts so, that they expire 1 at a time, much easier to get new contract and if it goes wrong you have alternatives for lower cash etc.

Thanks guys ! Really helpful.
