There are lots of issues for the borg to work through with the new ID system. The latest one manifests itself as a ‘best combo’ loop with unID’d artifacts. Got it fixed.
And the borg was holding onto some bad ammo when it should have been dumped.
And… Sometimes the borg might bounce between goals if he had ESP on. Basically, when a new monster is added to the known monster list the borg immediately cleared his goal (or current flow track). This was not always a good idea, especially if the new monster was 20 grids away and only spotted due to the ESP. Now the borg will only clear that flow goal if the new monster is LOS.
