I get this fatal error when going from garbage: Can't find model file 'physics\stul\stul_1ñ.ogf'.
I found the file that's causing it, will try to enter it again, if it gives me the same error, I will try to somehow change that letter in that file... If it works will upload a little fix... it seems this error was in the old builds too, so they didn't fix everything completely...
Its all Russian, it may not be compatible with worldwide or US releases. Luckily I have a Russian version of STALKER.
Now for my opinion (if you want it): Hmmm how to put this.. I don't want to give the impression at all that I'm saying its a bad mod or that I'm criticizing the mod makers. With that said, the maps are pretty awful and ugly, because they were abandoned by GSC in an unfinished state. The mod seems unstable, I get crashes in level transitions and such most probably because these beta levels contain a lot of errors. Getting these old maps to a playable and decent looking state takes a lot of work, and you can see now why the Lost Alpha people have been working for like 5 or 6 years now to fix these barely complete maps.
