I'm not sure how to help. This isn't a bug I'm able to recreate on my own.

Are you using the most up-to-date version of the Customizable Weaponry 2.0 addon? Make sure you have the current version of the weapons running on your server.

I'm not sure what you mean when you said "when the new round began, it passed." Do you mean after the round had ended and everyone respawned? Or after everyone had respawned and the round actually started.

It occurred accidentally, the person just did not see the picked-up weapon. I use the new version, in a new round it is a mistake passed. At the moment did not repeat, but there will be many people, will be frequent will repeat with others I believe.

If you can send video footage, I can be of more help. Otherwise, I don't know what to tell ya.

Everything seems to be working on my end. If I find a solution to your problem, I will post an update saying so.

[ERROR] lua/weapons/cw_base/cl_model.lua:1499: bad argument #2 to 'GetBonePosition' (number expected, got no value)
1. GetBonePosition - [C]:-1
2. unknown - lua/weapons/cw_base/cl_model.lua:1499

There was this mistake, unexpectedly when got weapon at the traitor, proskhodit accidentally and weapon because of which happened is invisible that it it became visible, it is necessary to throw out and lift.

4. unknown - addons/ulib/lua/ulib/shared/hook.lua:109

Came on the server, began to watch players, the mistake in the console began to send spam it, weapon in hands at them was invisible.

I will take a look at it. It sounds like a spectator bug.

Discovered what the problem was. Uploading an update to fix it now. Let me know if that fixes your problem.

2. unknown - lua/weapons/cw_base/cl_model.lua:1499

It is a mistake it is still relevant.

I can't help unless you provide more information about how you're getting the error. Just giving me the error isn't enough.
