<...>Could it be theymos removed the transaction, but not the Merit and sMerit added to Storx' account?
Thats what I make it. The @Storxs account is off by those 50 Merits (50 more merits on profile than what the 100 initial Merits + sum(TXs) can justify).
Strangely enough, @Storx received 51 additional sMerits over the following 2 days after the "incident" (from multiple users in 8TXs), but went missing since then (has not logged-in since 19/07/2018).
