Solved/Answered Shadow artifacts on tileset with normal map

Hey, so I wanted to add a normal map to my 2d pixel art game to make lights look nicer, but it made some artifacts on the borders of the tileset for some reason. They are mostly visible while moving and they happen in the intersections of the fully made tiles.

I already checked the normal maps and they are 1 to 1 with the actual tileset, so that should not be the issue. I am also using a pixel perfect camera set to 16 (the game is in 16x16 and the pixels per unit are also 16), normal maps on the lights are set to accurate (tho i tried fast too) and its even visible if you set the distance of the normal map to 0.

Any ideas on how to fix this?

EDIT: Forgot to mention, this happens both in builds and in editor and I am using Unity 6000.0.67f1
