I have the same problem with the batteries quest, but I'm already using an hopper. If you put the quest in fuzzy mode it has the best likelyhood of working, but taking the qds off quests with items with damage values would be better as Items with dynamic values are known to cause problems with HQM

You could probably do this without any Autonomous Activators, use dispenser for bonemealing, terrain smasher for breaking and openblocks dropper for placing. Idk if you need something to pick them up, but AA's arent neccesary
