Trading question - offered resources "refund"

[Batina]

Hello

Several times I have offered resources to some other player upon their public trade offer and never got neither acceptance nor decline.

In which "void" those resources linger and when do I get them back?

Regards

I.

Outstanding trade offers are automatically cancelled and resources returned after 8 hours

Thank you, that answers this question perfectly.
