Looks like the Team is well aware of some of the issues. Missing buys and missing tokens.
It seems like the Main Node of Steem-Engine is having issues. @inertia posted two screenshots one of Steem-Engine and one of his Nodes.
It is just a syncing problem and will be delt with. So if you are missing Tokens and or Transactions rest assured it will be taken care of.
Customer service on the team is important, your issue is definitely going to get attention. Fixing bugs can take some time.
