Hi,
on the provably fair page, the server-seed-hash and current client-seed don't show up (they do in the corners of the ticket) even though there's text that says they should. I tried to change the client-seed while I had a scratchticket loaded but unopened, but that didn't seem to recreate the ticket, nor did it give any feedback as to when the change would apply. The client-seed was changed correctly on the next ticket. Perhaps add a notice about when such a change goes into effect and/or allow the option to regenerate a ticket if the client-seed is changed after a bet is placed, but before any icons are scratched.
And for the promotion, my u/n is Rannasha
