- Whitepaper not found (tokensale page link): The requested URL /centrawhitepaper.pdf was not found on this server.
- Whatever that "ADD SHIPPING" button is, it does nothing.
- Fee information page is empty: https://www.centra.tech/centra-card-fees/index.html
- No info if first 1000 of 30 ETH contributors already reached: "We will also be giving the first 1,000 contributors of 30+ ETH a limited edition Centra Gold Card with additional limits, rewards, and benefits."

Quite unprofessional. Just my opinion.
