Small difference in Texture UVs when in object mode :( when i have my mesh in edit mode it looks fine:



(look at the concrete seams). But as soon i switch into object mode they get distorted: 



I just dont understand why. I had a bevel modfier applied earlier but it is applied as you can see in the modifier tab.
Does anybody know a solution?

Thanks in advance!
I fixed it accidentally, I just created a new mesh and joined it to the existing one with Ctrl + J and then the UVs updated and were ok.
