What is the reason for this visual error?

It seems like an error loading displacement maps? Maybe backup your save in game options, clear the cache on the page, and try again?

The problem has not been solved. I would also like to mention that some of the clothing works properly, but the issue is that during the game, various "toys" also break the model in the same way. Additionally, when attempting to change the scale in the settings, the location of the "broken" parts of the character changes.

P.S. Because of the Google translator, I didn't fully understand, are you suggesting to send the game saves?

Im saying you might need to reset browser data. Or try different browser and see if that works? If it is the brower cache.

Yes, I tried that, but it didn't work.
