I think this problem was discovered pretty early, as some copies are growing like odd white fungus type of thing, instead of typical disc rot.
I recall Nuit & Bruillard repressed the discs and replaced copies for free for a while but at least my personal copy is the rotten one.
Same happened with GRUNT "Europe After Storm" 1st CD edition that some copies later discovered to rot. So long ago that I am not 100% sure, but I THINK it was also repressed and copies replaced, but of course talking about something that happened back in 2001, it was not possible to pull back entire pressing. I got still couple copies that are original poster cover and discs totally rotten.
"Europe After Storm" been repressed since.. once or twice. Not sure. But there are 3-4 different editions and only if one happens to have very first one, with original discs, it may be effected. It was related to particular factory they used back then and not very common thing.
Anyways, if someone now finds out they need replacement disc for their Europe After Storm, I still got bunch of them...
