Here are the things that i found useful that may help you guys figure out whats going on:
GENERAL TIPS
Recharging flashlights: Press R while battery is in the inventory and you have flashlight equipped(same thing applies for guns)
Note: bug causes flashlight to perma break if the battery is completely finished
Repairing equipment: Requires repair kit, in the inventory hold left click and select repair on the desired item.
Upon death, XP and perks get removed, so until you are confident about your survivability, get all mushrooms and XP items(cockroaches, old meat) into storage as soon as you find them to avoid losing them on death, only consume once geared out.
Board all the windows in the main house and wait in front of the well until the water rises, once the well is red, drink and run back into the house, close all the doors and wait in the corner until morning time.(most of the time its safe if you dont move and stay out of the windows, moving around will give monsters line of sight form the cracks of the window).
I noticed that having power in the house does not make a difference between monsters coming in or not, so dont bother having the power on unless you know some scary crow monsters or other go through fortification monsters show up(never seen emm)
Power in the house makes it easier to deal with bad guys and thats pretty much it.
When starting a game, store all XP items and other items you wont be using immediately and explore without any valueable items to find all the major landmarks and locations.
Gear up and do not fear death, Only start gaining perks and carrying high valuable weapons once you understand which quests to do or where to go.(this does not apply to guns)
Guns do not lose durability so feel free to carry them.
