I'm testing a raid farm where villagers are being raided and supposed to drop gifts when I beat the raid but they just give me discounts.  I tested it with one villager and was facing him and being five blocks within the villager and my inventory had space left for new items but it won't give me a single gift.  I also put the villager in wandering time in the villager schedule.  Am I missing something or is it just a bug?
