Crashes stop campaign

[[XIII] Lucius Vinicius]

After beating the chapter "Tremors" the game crashed (it said "VICTORY!" then froze and crashed) and now I have to repeat a chapter that forces me to hurry (something I don't care for too much). Fortunately not all due to autosave, but still. That timing...
And it keeps happening, though after the first I saved right before the bossfight, so little harm, but still annoying. I simply can not proceed in the campaign.

EDIT: There's a longer bug thread already.
