[BUG] Generation stopped at 16%, version 3.4.0 #1464

Describe the bug
The generation process freezes at exactly 16% and never progresses. It eventually times out and throws the error decoding response body error in the UI.
I expect the world generation to complete successfully without freezing.

Additional context

I have tried generating a very small area (a single church in Berlin) with minimum settings (Mapillary disabled, no moving traffic, no traffic lights, default terrain).

The progress bar instantly jumps to 16% and then freezes indefinitely.

Network/Connection: I am located in Russia. I have tried using a browser VPN, disabled it, and also tried using "Zapret" (DPI bypass tool). The issue persists across all network configurations.

Logs: The log file (C:\Users\USERNAME\AppData\Local\com.louisdev.arnis\logs) only contains [webview][INFO] UI started entries. It does not log any errors when the generation freezes at 16%.

I suspect this might be a bug in the newly released 3.4.0 version, as the freezing happens on a specific fixed percentage rather than failing immediately due to a network timeout.

I hope for your help!
