What OpenArena version do you use?! Ayumi/Neko is deleted since 0.7.6, maybe?
you're right i meant the angelyss/neko skin
what i did now is: i removed the skin from the player-mature pk3.
i can still join pure servers (is this a bug? because Neon_Knight wrote i won't be able to), but all mature player models will be replaced by the std. sarge model, so its a compromise...
PS:
attached a screenshot of neko in action ...
