I'm using LWM's Deep Storage and Pick up'n'haul with misc bots and never had a problem before version 1.5 but now my hauling bots are moving items one by one to put them in container, it happened with wooden logs but I'm not sure if it happens with other items and I'm unsure about the source of these issues. The debug log gives me the following :

Invalid count: 0, setting to 1. Job was HaulToCell (Job_885002) A = Thing_WoodLog307049 B = (115, 0, 126) Giver = X2_JobGiver_Work [workGiverDef: HaulGeneral]
