For the last while, when I try to open the customization menu, I get a black acreen and this error in the console:

[[ mlp ] Customizable Pony Player Models] lua/pony_player/ppm/render_texture.lua:676: attempt to index a number value
1. renderFalse - lua/pony_player/ppm/render_texture.lua:676
2. PrePonyDraw - lua/pony_player/ppm/render.lua:122
3. unknown - lua/pony_player/ppm/editor3.lua:215

I have absolutely no idea what it means or how to fix it. Any help would be appreciated.
