The same ARK setting is written twice
Applies to ARK: Survival Ascended.
What it looks like in your config
HarvestAmountMultiplier=2.0 written twice in the same section
What causes it
ARK keeps only the last occurrence of a key within a section, so an earlier value you edited is silently dead.
How to fix it
These keys are set more than once in the same section: this. ARK keeps only the last occurrence, so an earlier value you changed is silently dead. Delete the duplicates and leave one line per setting.
