Portal 2 sounds in PTI workshop maps
I've noticed that on many workshop maps cave johnson soundfiles come up in English, even if I have a german Portal 2. Now my idea was to remove any of the english soundfiles from the original pak01_01 dir/ replacing these with German files. I've tried to create a vpk (drag and drop but also via commandline) out of a 1:1 copy of the portal2 folder except the english files. but no matter what I do, even if I try to pack only a few files, vpk.exe is crashing.
What did I do wrong? Any ideas?
There's always a vpk assert mdmp file created, maybe somebody knows how to get some debug info out of this.

So I removed them. Wasn't quite a good job which Valve did here as these sounds often overlap with the sounds the map creator has placed.
I also find the German sounds (especially the turrets) much cuter than the original. Cave Johnson's German voice is known from German voice overs and has probably a bigger voiceover baclkground than the orginal Cave
