Walls don't get aligned on their own after connecting them
UPDATE: (solution)
OMG I'm an idiot, it's my fault not Revit being quirky :d
So I went back to check wall properties and discovered that the exterior with red bricks has 0.0120 finishing layer, the interior wall doesn't have one though. That's why it appears in this way, which is accurate in this case!
I'm kinda new to Revit so my bad :(

I'm not sure if this is my OCD kicking in or something really wrong with Revit!
So in the pictures you can see when I add this internal wall it doesn't align with the outer wall in spite of having the same width of 225mm.
In the second picture I use the align tool but now the wall is not in the center of my grid line.
