Note of a couple bugs I've noticed:
-Can't do anything about the weapons stash until telling Frank about the plan. Found this while trying to check out the ghost town path, very painful to have to betray Frank. lol
-If you go the Help Nogas route, when you find Derek in the corn, it registers as if you don't know him/he's not "your master"/as if you came to Nogas on your own? Don't know if it happens consistently or if it was just a bug for me, as I haven't played that route again yet, but figured I'd mention it as I imagine it's probably pretty easy to look into and fix.
Yeah, when Derek tells the PC to go get the weapon's stash, I couldn't go do anything about the weapon stash/try to get the weapon stash when I went to Johnny's shop, didn't see any options regarding it in the Nogas town menu either. I had to go to Frank and tell him about the slavers and them plotting against the town first to have ANY options regarding the stash at Johnny's Shop or even in town/at the bar. I tried checking with Derek again and everything. I tried it about 3-4 times, couldn't get the options to show up without talking to Frank.
