Didn't receive vote keys

I voted 3 today and then the server was suddenly lagging really hard and went down. The server is up again just now and I checked on my account, but I didnt receive the keys.. And the voting sites says that I have already used my voted today
i believe this happens when the game attempts to give you a vote key, but as you are not online/logged off, you dont have an inventory, so cannot recieve the keys. same thing with winning the lottery but like how you do /(insert command here) (someone who's offline's name), it wont work. so it'd be like doing /give or /pay (insert name and item/amount) while that person is offline; making it display an error message and not complete. while it is annoying, i do not believe this to be fixable, unless by some chance there's a command that does it that i dont know about.
