I have one question. Why did you make the player base damaged by time?? Is it supposed to be environmental factors? If so, Why is it too fast??
I just had a frustrating experience when I repaired my whole 3 story base but I forgot to repair one of the main supports. It didn't take much time until I lost half my house and all furniture and Items included in this area.
I know its supposed to be part of the survival factors but maybe consider putting an option to disable environmental damage. Hmmmm.. or maybe make it deform the structure and not make it collapse until a creature hits it or something.
