Set food or enable the non food mode for sand crabs.
for moss giants and other dungeon npcs, start the script near the npc then add from nearby npcs.
for potions make sure to only add numbers so type 6 not +6, confirm if you did this please I will test again.
post settings for ankous it is working in general, did you enable any extra options such as safespot? Did you select the stronghold plugin? If so is your target tile walkable or in a wrong tile (wall?)
please use the bug report template if you have any bugs for faster updates
