For the 2nd time in a month 1 of my vendors decided he was done and left. Every time all of the items and gold are available through the house sign. The vendors are at someone else's house with rent set at 0, both set to renew. No the owner didn't do anything to make it happen and yes there was plenty of gold on the vendor. It seems completely random and each time it has been a different vendor. The vendors had been there for over a year with zero problems, until this last month. Any ideas what the problem may be or should I give up just trying to have vendors?
