It can be difficult (impossible) to say why a modification does not work if we cannot see exactly where and how you are trying to do it (meaning see the xml changes you are doing and where).

It is effecting the backpack window and moving it to the left instead of the mod slot window, and i can't figure out why. When this
<!-- Configuration for windowAssemble grid -->
<set xpath="/windows/window[@name='windowAssemble']/panel[@name='content']/rect/rect/grid[@name='parts']/@rows">10</set>
<set xpath="/windows/window[@name='windowAssemble']/panel[@name='content']/rect/rect/grid[@name='parts']/@cols">2</set>
effects the mod slot no problem, so I cant see why windowAssemble is effecting the backpack and not the mod slots like it does with the rows and columns.
