Greetings!
Thank you for bringing this to our attention, after taking a look at the issue we believe that this is an issue of presentation. If Barik's reputation gets high enough to the point that it is close to the lock symbol (visible on the Reputation UI screen), his reputation gain will no longer appear because he cannot exceed that lock without a very major gain in reputation. Thus the notification of him gaining rep (which he would otherwise gain in this particular instance) does not appear. This has been brought to the attention of the devs and we will see about adjusting this to make it present better. Thank you very much for your support.
-Best,
Ian
