Thanks for logs. I have few questions to you:
1. B is not working for crew skills or players damage list, or both?
2. Do you recognize something specific that happened when it stopped to work? For example start to play some clan battle types, or premium tank, or tank with auto crew return, or tank with autoequip devices...
3. It stopped to work during that first battle or between it and second one?
4. In logs I have found that perhaps you playing on NA client, right?
Ad. 2. I already have bug report that crewSkills is not working when auto crew return.
Ad. 4. On previous patches I also get reports that my mods are unpredictably hiding on NA. I have asked some guys to perform test on that version. No results yet. If it is still the case I will finally download NA and try to debug.
