Need help) In game hair tie issue

Hi.
When you change the shape of the mesh, you should always remake everything that is responsible for how it behaves, if there is a difference. For example, these braids are affected by the head bone only, so there is no need in changing the rigging. They are vertex painted with 007F02, as they should be. The uv_1, on the other hand, differs, so you should re-make it for the parts of the hair that were modified.
- in uv editor enable sync, switch to uv_1;
- disable Limit selection to visible, select one braid as best as you can, press Ctrl L to select all of it;
