No Grass after voting.

I voted when I wasn't on the server. When I came back to it, it said I had received a voter crate key, another grass block, a voter crate key and 5 extra grass blocks. When I checked my inventory I only had received the voter crate keys. Did this happen because I was offline? If possible I would like to have my grass blocks back.
Below I will provide a picture of what happened.
Thank you,
Rafaww

 

Yes it's because you were offline, but I can refund the grass.

 

Thanks! When can you do this?

 

I'll get on now and refund them.
