Me again, I agree that there maybe many candles or tallow around but at the point of me needing it I found a base and as I noticed I was on 13% food/water I decided to make a campfire not realising that I needed tallow, when you start the game you get a torch which is fine but since you changed it and people aren't expecting to know you needed tallow that's when the problem starts, I was running around in the desert collecting yucca for food and blueberrys for water but because I was in the desert I had stage 2 heatstroke so I had to eat and walk out of the desert, losing water quicker than I was gaining it. Needless to say I made it and bought a candle from the trader.
On another note:
Here is what I am thinking, you seem to have made looting bookcases longer, not sure why, also there are inconsistencies in the available space for certain containers, like for example, small chest storage and large boxes hold the same amount, surely a large box can hold twice the amount of a small chest.
