It's neither nerf nor bug, but rather intended to be a rebalancing that shifts some of the incentives away from spamming low-level missions (even after you have high-level followers), in favor of making high-level missions more rewarding.
We made two changes:
Level 90-94 missions will only award a Bag of Salvaged Goods (level 1 reward) regardless of the level of your Salvage Yard.
Successful Level 100 missions will now always reward a salvage crate appropriate for your current Salvage Yard.
Level 95-99 missions are unchanged. On balance, players who are trying to increase the item level of their followers should be receiving a similar number of follower upgrades as before, but hopefully with a bit less emphasis on logging in every hour or two to cycle through quick low-level missions.
