Maybe make it so some really expensive block was indestructible, just so a single raider couldn’t take absolutely everything, or maybe make it so you get them based on playtime, just so longtime players have better protection for the greater number of loot they have. Also, I think it would be nice to have it so at the end of the siege, a hopper or chest would appear. Inside would be a book or something that told you what was destroyed. You could then place those materials in and it would automatically place them. It would be easy, faster, and no dupe glitches. Idk if that’s possible, hopefully it is.
