weapon_scripted doesnt have worldmodel animations.

[Cayama0811]

Describe the bug
When you use any custom weapon that comes from the class weapon_scripted the third person animations wont work, the character stays in tpose.

To Reproduce
Steps to reproduce the behavior:

1. open any map and add a bot using the jbmod_add_bot command
2. give it a leafblower, since it comes from weapon_scripted
3. See error.

Expected behavior
Player should be able to set stance types to their weapons, so they work in thirdperson properly.

Screenshots

As you can see here, we are both holding the leafblower, the bot doesnt have any animation.
