[Subquake's Undead Legacy]

Hey Subquake, I'm really enjoying this so far, I just wanted to ask a few questions about how some of this mod works.  

 

I think the lockpicks are new with this mod, right? I don't remember seeing these in vanilla.  I've tried using them on every door I've found, but I'm unable to use them.  Are these only for other player placed down doors/chests?  Or is something broken with these, or am I not using these right?

 

I have a problem where I've taken over a small house poi as a temp base, and wolfs and dogs and zombies are spawning close and in it sometimes when I come back.  Is there a land claim block like in vanilla helping to prevent this, or some equivalent? 

 

I was having some trouble trying to plant seeds earlier, I don't think I was able to plant them just in the ground.  I read the journal entry for farming and I think it mentioned I needed to get the ability to do it from something, but I was not able to find a perk or skill or anything in the character menu.  Is this something I just have to find in a loot drop?

 

Thanks a lot for all of the work on this mod, it's been a really refreshing experience playing this game again.
