I downloaded your prog to compare the files. Then i downloaded the newest uibuilder via the eq2 updater. next i opened my maintained.xml and immediately saved it without any changes. The result is a size change from 23kb to 30kb and lots of changes as i can see with your program. Why is the uibuilder doing this ? and what can i do to avoid the unwanted changes ?
left side is the original, right side is the copy, red lines are the unwanted changes the uibuilder made.
PS: Are you guys using the uibuilder too to create your mods ? are you having the same issues ?
