xref and floor generator issue

[jonasmotiejunas]

Hello, it's the first time i'm working with xref'ed objects and i came across this issue i'm trying to deal with. I've create wall tiling with floor generator modifier and aligned each of them with XY offset sliders (image1), and as soon as i add those objects to another scene as xref'ed object or xref'ed scene the aligment is gone(image2). Is there a way to keep the original alignment? I found that converting to editable poly helps, but it would be nice to keep it editable in case i need to change tiling. Adding edit poly modifier doesn't help. Any thoughts? Thank you in advance.
