Describe the bug

TF2's grappling hook's cable appears invisible.

Steps to reproduce

Steps to reproduce the behavior:

1. Enter an arbitrary map (ex. map itemtest)
2. Enable the grappling hook with the console command tf_grapplinghook_enable 1
3. Equip the grappling hook and use it

Additional context

Previously reported on the TF2 Classified bug tracker as tf2classified/tf2classified-issue-tracker#943. I have reproduced this issue on Mapbase's unmodified SDK.
As the above issue mentions, whenever the cable would be visible, the error message Material cable/cable_red has bad reference count 0 when being bound. (or cable_blue for BLU) is printed to console.
