Since yesterday's patch, the work orders on my buildings with followers haven't been giving the expected amount of materials as they should. I've kept a follower 100% of the time in the barn, tannery and the tailoring building, and the barn has been giving me only 15 raw beast hide for every work order. Furthermore, the barn with a follower was supposed to give a higher chance of savage blood, but I haven't noticed that all, having received even less savage blood than usual (rng will be rng). The tannery and the tailoring building sometimes give 2 leather/cloth but sometimes only give 1. The followers I have in the buildings are all level 100, epic with 654, 630 and 615 ilevel respectively.
Was this a change for 6.1, where level 100 followers wouldn't have a 100% chance of awarding the bonus? There is nothing in the patch notes that would suggest this change, because, I repeat, I've had the followers in the buildings all the time, before and after the patch.
