Merchant Archive

I have some questions and concerns about the merchant xp. I have read over many other posts but haven't found an answer to this.

I read the guide and I should be getting 150 per vendor per hour, I had 5 vendors so that should be 18000 a day, I was off for 4 days so I should have come back with 72000, but I only had around 14000 xp. A few weeks earlier I untrained merchant though and went up another line and before I untrained it I had effinency II, and according to the guide there is a bug that makes it so all npc vendors don't give xp. So I'm wondering if I had EFF II and untrained it does the bug still effect me or is something else just going wrong here.

All of my vendors were stocked with atleast 50 items. All vendors were payed with 5000 maintance. I had 4 NPC vendors and 1 droid vendor. I have 2 vendors in another PA hall, 2 in My declared residence Large house, and 1 other vendor is a friends large house. 1 small house with an access fee. The PA hall vendors were regulary visited.

If someone could help me out here , my holo told me master merchant so I want to get this through. Some of the other posts I've read are saying I need to be logged on and in my house to get my xp, but also haven't heard any confirmation if the xp is just be stored until the vendors are loaded, by someone entering the house.

Thanks for the help.
