At least that's what I have found in the Druid Grove, first I talked to the halfling trader, can't save, talked to Dammon, saves working again. Also, I am running mods and such...
Hope this works for you guys.
Edit: so yeah, the issue in the Druid Grove is the Halfling trader.
This, unfortunately, did not work for me.
If I load the game and talk to no vendors I can save but if I buy/sell anything then it breaks. Talking to subsequent vendors has no effect on the broken save capability.
