Aha, so you don't like it, and therefore it should be removed from the entire game?
You realise how minor of a part this is in the game?
But, fright not, my peculiar friend. It is elementary, an easy fix for the everyday Toribash addict. I have provided you with a barrage of options to help you find the light in the darkest of times, and fight for the right to be an individual. Yes, you have that right! You can make a change! You can make that ugly ground texture into your own personal slave and make it kiss the floor for you whilst you kick it in the face for its incompetence. Together with your ground textured friend, you can go out in a war, for the extermination of all ugly ground textures. You can create a world where they are but an eyesore for the community. You can be the revolution in the world where corrupted floor textures walk the face of the earth without a care in the world.
Or you can just;
1. Play with the damned texture and ignore it (your best choice)
2. Stop playing Toribash (and come back in a few years, as the tale goes)
3. Downgrade your client
4. Buy a ground texture
5. /opt floortexture 0|1 (might be outdated though)
