Error adding arrangement

[J1nn]

i keep getting this error when attempting to add an arrangement xml ive just made.

i have no idea whats wrong. my best guess is possibly an issue with the gp import? i made this with the versions of eof and the toolkit ive been using so updating either should not have been an issue. doesnt happen with other xml's i have.

 

EEdit: can this be moved to the EoF area. i just tried loading the xml as a rocksmith import and none of the notes actually show up in eof so im pretty sure the problem is entirely an EoF error
