if u use csdm then set db_deathmatch to 1 ... deathbones is not a replacement for csdm (or an other dm-plugin) ... this cvar change the internal handling for the skeleton (this is different for normal-play and dm-play)
@ali_zkz
have u restarted your server ... i mean full exit and no map-restart ... or the contens of the cvar ist wrong ... db_deathmatch is only 0 or 1
