Normal maps issue in Unity

Hi!
I'm having a lot of fun with Crocotile 3D, but I came across some weird issue I'd like to share to try and get some help.
I made an object in Crocotile 3D with a 32x32 tileset, and made a normal map based on this tileset.
Once imported in Unity, I made a basic material using URP lit shader, put the tileset as albedo and the normal map as well.
Unfortunately, the result is not what I was expected, see for yourself:

While the diffuse is mapped correctly, it's not the case of the normal map.
They're supposed to share the same UVs, am I missing something here?
Thanks in advance for your responses!

I've never used normal maps before, so I'm not sure. I also don't know much about unity. Maybe someone else can chime in if they know how to make it work. You can also try asking in the crocotile discord channel if you don't get any response here. Sorry I couldn't be more of a help.

I remember him discussing it in the Discord channel, and he was able to fix it. From what I understand, the issue was related to the Normal map texture size being different than the Diffuse texture. When he realized that and made sure they were the same size, it was fixed. But maybe he can provide more information if he wants.
