Final Fantasy XIII-2 save editor (possible glitch)

i Dont know if the save editor is causing a issue or if my save just has issues but all of a sudden now my artifact i had has disappeared and i cant open the time gate in new bodhum but if i go to make adjustments my original stuff is corrupted and my levels i had saved are reset to level 2 again i am hoping i can recover a original backup to see if the damages are undone and see if i can reaccess them after opening the time gate and not erase any artifacts i collected\
note: i was using the save editor 3.5.0 by Jappi888
