I guess you are already downloaded Sanderling project with adapted memory reading so you need to go there again, open up Sanderling → Parse → ModuleButtonTooltip.cs → line 40. You will find the list of items that considered as weapon.
If i get it right you are using Tachyon Modulated Energy Beam I which is not presented in the list.
You need to add something like “Energy Beam” and rebuild project then update Sanderling.dll in ABot lib folder.
