Found a bug if editing the world in the middle of the game, traits that change stats values get also aded to the world edit causing it to acumulate with each new game and edit.
i created the fertility trait that increases starting fertility by 100 and the base starting value for fertility is also 100 (so 200 if starting with the trait) but if i chose the trait and click edit wotld the vase fertility value in the stat gets changed to the new value.
resume:
base stat in world edit is 100, open world and chose trait hitting confirm, hit world edit button in game, base stat is now 200 in the world edit.
Also i have a sugestion for the trait system, Conflicting traits, on the traits themselves other traits are shown (like entities are shown on locations) and chosing a trait on game start blocks the player from chosing any trait marked as conflicting for that trait.
