Well at least post in the right fucking thread then, no need to start your own. There's a perfectly good thread relating to Awesomemod bugs, conveniently placed in the Awesomemod section. You might have seen it, "The New Bug Thread".

I can't explain it but my collector helpers only work if they belong to the Sim who is holding them. If they transfer out of my Sims inventory they won't work with another Sim. Are they supposed to work with any Sim?

Did a Sim in the active household die, and did that Sim have a collector? I bet when another Sim died his/her inventory was emptied into another Sim's. When this happens, the living Sim can't use the collector helper, because they didn't buy the ability. Check if your Sim even has the ability or not. If not sell it. I think its worth over 4,000.

Murphey's Law. As soon as I said it and went back to my game, he stopped moving. However, by then the guy who found it moved out of the active household with his two kids. That's the only thing that changed. He hasn't moved for a while now.

Maybe I'm just an idiot, but when you go to your Sim's inventory and you click on the collector helper thinger, you can set it to what you want it to show? Honestly, I haven't had the game long and have only had two Sims get the collector helper reward thinger, but I swear I set one Sim's to only show seeds, and unless I changed it after that it only showed seeds. However, I could be wrong.

There are two things I noticed with my Sims. First, I didn't get a magic gnome guy unil I had a plant planted (Sim planted, not through the build mode) on the home lot. Also, my (one and only) gnome has never ventured inside the house (does a foundation matter?). He moves almost every night, but he runs around and then poses somewhere near the planted garden. Perhaps there can't be a fence between them and a planted garden (gate included?)? Honestly, I don't know. My gnome has been active ever since I got him (and I renamed him as soon as I got him, so that doesn't stop them from moving). I just thought I'd share what happened to me.
