curl -s -X POST -d '{"jsonrpc": "2.0", "method": "account_history_api.enum_virtual_ops", "params": {"block_range_begin": 1838272, "block_range_end": 1838276, "group_by_block": true, "operation_begin": 2, "limit": 2, "filter": 7810340274393554548}, "id": 1000}' https://api.hive.blog

curl -s -X POST -d '{"jsonrpc": "2.0", "method": "account_history_api.enum_virtual_ops", "params": {"block_range_begin": 1838272, "block_range_end": 1838276, "group_by_block": true, "operation_begin": 2, "limit": 2, "filter": 16384}, "id": 1000}' https://api.hive.blog

Returns two operations for legacy, and for hafah no results. Later call for hafah also takes like 3-4 seconds (on my machine) which itself might be sign of some issue.
