Hello Hive account@truce,
There was a bug in the code which didn't count the VESTS (Hive Power) of accounts and only donated the liquid balance.
There have been some discussions around this problem and there is a plan for it. The missing funds will be distributed in the coming days.
It's a shame we didn't test it fully. It was kinda hard to test the airdrop code but again, it's our fault.
