Hello, (sorry, this post is old, I ignore if you have found how to resolve problem since)
Farm-path > I'll add option like "No hotspots, is path" (and add possibility to record path) in grinder, killandloot,... You can set search radius with c# code
wManager.wManagerSetting.CurrentSetting.SearchRadius = 9999;
(add step type "RunCode")
Kill+gather > To gather and kill, add step type "RunCode" with the code:
wManager.wManagerSetting.CurrentSetting.ListHarvest.Add(232544);
(replace 232544 by your game object entry id) Add quest type "KillAndLoot" and pulse it (like here: http://wrobot.eu/files/file/486-garrison-farm-minesherbs/ )
( to remove game object at collect, use this code:
if (wManager.wManagerSetting.CurrentSetting.ListHarvest.Contains(232544))
wManager.wManagerSetting.CurrentSetting.ListHarvest.Remove(232544);
)
