Thanks for the suggestion! Unfortunately, the same thing happens without other players. The game complains about the grunt_i pcx file and when i change my skin to Claymore, for example, it starts to complain about claymore_i pcx file.
These are the default skins and still the game complains about not finding the files, (bh0.pcx, bh100.pcx etc.) even though they are present in the Quake II\coopordie\pics folder. It specifically complains about not finding "bh0_bump.pcx". What are these _bump files? As i said, i manually copied the files and added the "_bump" to the file names, and it worked, the game wasn't complaining about them anymore, excluding the player skin file.
The warning reads "Can't find pic players\male\grunt_i.pcx_bump", and creating a file named "grunt_i.pcx_bump" in the correct folder doesn't fix anything
Is it just Q2XP changing and slowly becoming more incompatible with CoopOrDie?
