I am currently having a problem with my werewolf follower getting hostile too easily.

Information:
*The follower is Aela the Huntress, and I'm using ESF:Aela (Nexus ID:11450) to improve her. That mod is also making her able to use Beast form.
*The problem is that when both Aela and I (or one of us!) are using werewolf form - Aela turns hostile after only 1 hit from my Dovahkiin. This happens regardless if we're in combat or not. It is very inconvenient.
*I had a similar problem on my old playthrough. It actually eventually got even worse on that playthrough - Aela got hostile the instant I transformed. That is not the case (yet) on my current playthrough though.
*The author of ESF:Aela has tried to help me with this problem. He suggested some console commands that I tried, with no success. I tried these console commands: getrelationshiprank player (returned 3, as it should), getgamesetting iallyhitcombatallowed (was already set at 1000), sifh 1 (set ignore friendly hits. did no difference), player.getshouldattack player (returned 0, as it should). He did also suggest trying the No Friendly Fire mod (Nexus ID:22538), but it didn't help.
*ESF:Aela is NOT the cause of this problem. It works for other people. And on a very early save it did work for me too. (The issue acually just randomly appeared between two saves - and I did nothing strange and didn't install any mods between those saves)
*Other, possibly related, mods that I use (Disabling them does no difference though): Werewolf Upgrade (Nexus ID:5866), La Femme Lycana (Nexus ID:7169), UFO (Nexus ID:14037). (Should I post my entire mod list?)
*I use the latest Skyrim and SKSE versions. I have all DLCs.

Any help, suggestions, questions or information would be highly appreciated!
