if you are using the ZR plugin:

1. open the sourcemod - zr - weapons - weapons.inc
2. find stock WeaponsForceClientDrop(client, weapon) and change CS_DropWeapon(client, weapon, true, false); to SDKHooks_DropWeapon(client, weapon);
3. recompile zombiereloaded and test it

if you are using CS_DropWeapon in other plugins, change to SDKHooks_DropWeapon
and if you have a plugin that uses CS_OnCSWeapon, unload it. (until a new sm build comes out)
