Ok, strange problem here. Under v0.8.1b, I can create lotteries fine, create a sign for it, and when I right click it does prompt me how many tickets I'd like to buy, but no matter what I enter in chat, it does not respond in any way until I right click on the sign again. At that point it cancels the transaction. I also noticed that even once it is cancelled, I can no longer use chat for chatting. Messages show up in the console, but not on my client. I downgraded to v0.8.1a, and I do not appear to have any of these problems. Did something else change that could be causing this?

Mine Does the same thing but i don't want to switch to the later versions because the time countdowns and pot amount wouldn't be on the signs.

This bug has been fixed
