That's odd. It seems to be trying to load data beyond the specified range and borks out as it fails. I'll investigate, but it really shouldn't be doing that anyways. Which MH4U ROM is it and have you altered the original template in any way?
EU Contrast scene release (trimmed). Only thing i did to the original template after downloading it was removing the couple of blank lines at the top that prevented it from being opened in sky army knife. Other than that nothing was changed in it.
I did get it to work though as per my edit in previous post which is kinda odd that it worked alone in its own txt file.
Doesn't matter now anyways, the spacing shouldn't be a problem anymore.
