I was playing Lost Planet 3 when suddenly I got the "Platform/Roman Bug"
It happens halfway through the game, right after the NEVEC ship arrives.
SO, my game stuck and I had no backups or previous saves to fix the problem.
I tried Hacking the Save File, but even the save editors were not working with that save, aparently because it was a save from inside the mission.
So I had to play the game all the way through again, and so that no one never has to pass for what I had to do, I'm posting my backup save right before, and after the aforementioned error.
The specs from the Save are:
Albine Tarkaas: 8 (7 spent)
All weapon and rig upgrades bought so far
All Kovac missions completed
secondary ammo: 5000+ (each)
Souichi's Mementos Found and Delivered
Before the Platform Error:
Lost Planet 3 - Platform Bug Backup.rar
After the platform Error:

I hope I helped someone avoid this hateful problem.
