Recluse - From what I remember the red bars appear when decompressing a new terrain set. You're obviously trying a mission which uses the terrain set that's already decompressed. The stock pre-scripted single missions, I believe.
Yep.. I specifically chose one that didn't need decompression. Wasn't clear from the original problem that it was during decompression.. sorry
Also, as you may know, I mount an .iso with Daemon Tools, so decompression is probably quicker anyway. Could be a scratched CD or something if it is decomp related. In that case, I would ask if the issue occurs on all the terrains (NTC is on Disc 1 while the AZR terrains are on Disc 2)
