Anyone have much experience with these? I made 5 of them total and took them out into the wetlands to try out. Would right click on it, set the targeting circle on the ground, received the messages about would be armed in 10 seconds, would be armed in 5 seconds, Goblin land mine is now armed, and watched time after time as different monsters walked right over the top of it, next to it, even had a raptor jumping on it and none of them ever exploded. What is the deal? Am I doing something wrong? Please help, my level 27 Dwarf hunter only survives the areas I hunt because of my supply of explosives in tough fights etc and doing 400 damage to something would be great. Thanks in advance for any and all help.
