I am confused about what the hell just happened in this ICO / TGE.  There was a hidden cap.  They changed / raised the hidden cap DURING THE EXPECTED ONLY HOUR.  People donated after the hidden cap was hit.  

What was the final hidden cap?  How many total ETH were sent to the contract?   The people who contributed after the hidden cap was hit, they didn't get tokens, right?  But the eth they donated is still locked up in a 20% / 80% contract split for a year?  ELI5, please.
