Hello,
Yes, we can now see what's causing the issue. The homepage limits to showing 400 transactions to prevent an overflow. We were working on a "Pages" plugin due in less than a day or so, though, we were not expecting over 400 investments in the meantime.
While we work on the new plugin the limit has been raised to 1000. Please have a look now!
Also, did you delete your cookies/cache? What is stopping you from seeing this investment in the "My Investments" tab?
Thanks for your patience, and sorry for the scare!
