I noticed strength does not seem to affect the damage of thrown daggers. Negative strength gives no penalty, and positive strength gives no bonus (similar to crossbows). Is this working as intended?

It's possible that all light thrown weapons are functioning this way, but I have not checked.

I'm really enjoying this game, thanks to the devs for making it.

Daggers have not the Heavy Thrown flag, so thay use Dex and not Strenght
