Weird murder error

[ERROR] gamemodes/murder/entities/entities/mu_knife/cl_init.lua:40: attempt to index field 'Emitter' (a nil value)
  1. unknown - gamemodes/murder/entities/entities/mu_knife/cl_init.lua:40

[ERROR] gamemodes/murder/entities/entities/mu_knife/cl_init.lua:17: attempt to compare nil with number
  1. unknown - gamemodes/murder/entities/entities/mu_knife/cl_init.lua:17

both of them are in Murder gamemode, and they suddenly appeared without reason :confused:

When the last time you updated Murder? The first error was fixed a while ago.

may i add, they appear whenever someone throws the knife
