Reputation in Uzhitz and Merhojed Update 1.8

I am going for the king charming trophy and am struggling with reputation in merhojed and uzhitz. After 20 transactions with traders in each area with tipping them each time, my reputation has not increased at all. I am at the epilogue quest, I just beat the game, so I reloaded my previous save to get this trophy. I did not steal anything or commit any crimes during the story, I completed all of the side quests in each location, and am aware of the merhojed fast travel event to increase reputation with soldiers. Has anyone else had this problem? I am curious if it could relate to end game status or the new update. Please let me know. Thanks!
