According to my settings, it should be 1xp per gather, right?

That being said, I'm getting 2 xp each time I gather a corn or pumpkin. What am I missing? 

you're using a fraction in

ResourcePerLevelMultiplier​

nivex

you're using a fraction in

ResourcePerLevelMultiplier​

which needs to be a whole number
so the plugin is not loading your config file

Actually, that issue is only happening on corn & pumpkins, not wood, stone, metal, or sulfur. Haven't checked any of the berries or hemp. 

And that 0.1 has worked very well, actually. It awards +1% per level after 1. So, during the day, if you're level 9, you'll get a +8% bonus to things like wood or stone, for example. It's a bit tougher on things like pumpkins, which round up, so instead of 1, you'll get 2. 

ok, I wouldn't worry about it. I am working on a new version that you're testing which shouldn't have that issue once finished
