I made a new weapon using the grenade base.

I set the ID to TK.

I set the weapon to the inventory list for Moira but when i open the shop it doesn't show even if i wait for the shop to respawn.

You have to add it to here merchant container

Hope it helps

Thanks Persidon

I set the item to

the vendor
vendor chest buried
vendor container

i waited 3 days but it still doesn't show

I imagine this is where you looked, but just in case...

I'm probably not the one to give out any good answers, as I am very new to it myself. I'm not at home to even glance at this stuff, but the only thing I could think of off hand is the lists based on levels - could it be that the new grenade is set to only spawn if you are at a high enough level? This might have nothing to do with it, but just thought I would throw it out there.

Hopefully a brighter, more experienced mind can help you out. =)

If this mod is just for you, you can go the fast route and just add it to Moira's existing container, which I think is the broken cabinet in her shop, next to the counter.
