I made a Black Market trader no problem, made a Helicopter trader both worked well for a week. Made another trader, trader showed but with no Menu Option to trigger,checked my other traders, the Helicopter trader was missing the option also, rewrote them both a couple times, no change, then asked someone who has had his own modded server for years, he went through and fixed what the thought was wrong,, no change, I uninstalled the trader mod, deleted all the files, reinstalled and still no Menu Option except for the one Black Market.
