Wait. The test version of N Terraria is for Terraria 1.3. Due to some changes on Terraria content folder brought by Terraria 1.4, N Terraria test version doesn't working anymore. It would be necessary for me to review what is missing, or changed on Terraria 1.4, and then make the mod load It.
As for the Free Mode not giving you stat points, is because It works like this right now, let's see if I can explain.
So... Every Free Mode Rank has 10 exp bars that needs to be filled, and each exp bar is the same as 10 levels, so filling one exp bar is like leveling up 10 times.
Due to the exp bar change this mod got a number of updates ago, you possibly can't see those exp bars anymore, but each 10% of exp is like leveling up 1 exp bar.
To gain a status points, you need to level up 100 times, in other words, rank up your character.
It got clearer or did I made It more confusing?
