I know, I know, this is gonna sound silly but.... I'm thinking about all the new unusual names we've got in the pool now with gargoyle vendors and wondering if there's a limit of some sort on used NPC names each day and if your vendor's name doesn't make the list he gets cut
many pardons about randomness, I clearly need more caffeine lately
My guess would be that it has something to do with the storge upgrades. We know that there is an issue with trading a house that has more vendors or lock downs than a standard house should have.
Let me outline this.
If you have a buyer and a seller that both carry the 60% storage and vendor Upgrade, You need to dismiss the enough vendors and unlock enough storage to ge thte house below the original max for storage and vendor count in order to trade the house between the accounts.
I can see how this might somehow roll over to the vendor issue we are dealing with at the moment.
I would like to say I have never lost anything do to this as it is always reclaimable via the house sign
what does cost is re renting the spots several days a week for the weeks rent.
