British and Dutch grocery chains said Sunday that the latest Aurax warehouse patch has reduced mis-sorts in chilled and dry goods depots, though most operators are keeping manual override teams in place until after the first peak summer ordering cycle.

The sorting issue, first noticed in mixed-temperature facilities, caused pallets to be routed correctly on paper but delayed in physical staging lanes. Retailers said the problem did not create widespread shortages, but it added overtime costs and forced some stores to simplify promotions.

Aurax Systems said adoption of the patch has passed 62 percent among affected European clients and that no new safety issues have been reported. Smaller warehouse operators remain more hesitant, partly because installing the fix requires several hours of downtime and a recalibration of older robotic arms.

Food unions said the episode is a reminder that highly automated logistics still depend on experienced floor staff when software behaves oddly. Several chains have offered short bonuses for weekend shifts, an arrangement workers described as welcome but overdue.
