Bug Report

Please answer these questions before submitting your issue. Thanks!

In the current implementation(master, v4.0.2), after region splitting, we add some related nodes to the frontier;
however, after region merging, we do not remove the overwritten nodes, which leads to an increasing number of nodes maintained in the frontier.
