With mods I guess? The error: info: CWldSession::DoBeat() unknown entity id (0x2ff0049a) supplied in a pose update. warning: Error running lua script: Failed to attach entity xss0304 to /projectiles/sinker/sinker_proj.bp on bone 1 stack traceback: [C]: in function `AttachBoneTo' ...projectiles.nx2\projectiles\sinker\sinker_script.lua(46): in function `StartSinking' ...projectiles.nx2\projectiles\sinker\sinker_script.lua(28): in function <...projectiles.nx2\projectiles\sinker\sinker_script.lua:26>

Still same error? What have you tried to solve it?

I have idea, when i try it in sandbox, then i sumulate problem and, can use replay and if someone deliver me some change on experimental graphics i can test it.
