I am experiencing this very same problem, Tome of Influence and Letter of Commendation used yesterday, neither gave the influence to my guild. I was 100% sure to be representing the guild at the moment. Guild influence history doesn’t show anything regarding using these items (it does show same items being used by other members several days ago succesfully), but my Character screen, achievements section Community achievements “Active Guild Member” shows that the influence was earned from using the items, yet it was never succesfully actually transferred to the guild.
The issue is somewhat worrying me as there is real money involved in buying the DD edition and the bonus item doesn’t seem to be working as supposed, so hopefully would hear if people have got any help regarding this issue.
