The branch field of non-consensus operations is set by default by the Octez client to HEAD~2. Setting the branch field to HEAD or HEAD~1 may result in the operation not being included because it will not be anchored on a block belonging to the chain. (The blocks at the current and previous levels are not necessary final.)
Without this, you will often end up using a branch that is orphaned and not finalized by consensus. This results in missing txs that had seemed to be injected successfully, etc.
