These quests are totally broken and exploitable. The code is bloated with redundant entries that should have been addressed by creating master items and extending those rather than coding each individually. There should be checks written in to prevent multiple 10z, 100z, and 1000z quests from being done at the same time as I have tested crafting and completing 300 10z quests simultaneously. There is no limit in the game on how many quests can be active at the same time that I have reached so far (400+ in testing so far) and it literally takes more time to read and accept each quest than kill the whole 10 zombies needed to max out every attribute and perk.
