egarding testing the visual layout of your buildings: Build the "wireframe" with frames first. "Fill" the frames when the silhouette looks like something you want. You can pick up the basic frames (wood, cobblestone, rebar) up and reuse them as long as you do not start to upgrade them with material.
I do this first but then when I upgrade it sometimes I do so accidentally and then I have to tear it down to match the rest of the blocks. I have an idea to start building outside of my fortress as a test so then collapsing the test structure with a stick of dynamite, as I will not have to worry about destroying part of the my fortress, and dynamite is a good way to destroy a good structure but I found out the hard way and killed myself.
My thing is perfection and symmetry these two things rule my building so this is just me and not so much a defect of the game.
The blunderbuss sounds cool I think they were before muskets in real history, a large funnel end and pack it with gunpowder I guess. What would really be appreciated is a silencer (please don't say anything I will find out on my own) if I can find one. i always use my bow or crossbow when i can and usually when I enter a building with the zombies sitting in the corners and sneak up for a headshot kill with a steel arrow.
The excuses are real, its just my own weakness that keeps me from stopping. I quit smoking in 2015 without patches or gum, I just said to myself I do not need to smoke and that was all it took. My mom was surprised because I smoked for 33 years and I smoked 5 cans of bugler (rolling tobacco without filters) a month, so I have willpower but I guess I just need to force it. When I do exit the game I save the save folder to another folder and this has kept me safe when the power went out and I restarted my PC and the the game I was in the same location with the same map and buildings but my character was reset to the start, when my video card glitched due to overheating (this game taxes my GTX 1080 like no other game) and I hit the escape key, then reset my PC I was right where I left off, seems I guess without hitting the escape key on power loss the game resets the character, the character is not updated every minute like most everything else, I know this because I had a program called Watch Directory that was monitoring the save folder and copying and renaming the files that were changed and there was a huge amount of writing in the save folder during game play, some at every minute and it got to the point that I was getting too confused with a folder with 100's (depending how long I was playing at the time) of copied and renamed files and some were not updated every minute, I forgot which ones, but trying to piece the save folder back to an earlier state I would see from say 11:33 to12:20 every minute there was a new file and a few were 8:22 or 6:07so they never matched and it was hard to piece the save back together, so now I just stop and save the folder manually.
