New block loading is a problem

[D3it7i]

Expected Behavior

I tried to load it with a computer version of the site, because this version of the computer map was loaded perfectly in the previous version.

Actual Behavior

But he had a problem in the new version, and there was a lot of wrong information on the console.

Steps to Reproduce

Select a map created on the computer to put his load on the server. Then you will see an error message and console empty.
