Name on main page doesn't correspond with name in lobbies

[HeinzNepe]

Describe the bug
My name on the home page is "HeinzNepistan".
When joining a lobby, I'm called "67 Cringelord".
This persists only if my name contains something ending in "nepistan"

To Reproduce
Steps to reproduce the behavior:

1. Go to main page
2. Fill in name ending in "nepistan"
3. Create a lobby
4. Scroll down to the name section
5. See incorrect player name

Expected behavior
Expected to see name as "HeinzNepistan"

Screenshots

Desktop (please complete the following information):

• OS: Windows 11 25H2 build 26200.8037
• Browser: Vivaldi (chromium) version 7.8.3925.76 (newest at time of report)
• Game Version: 0.30.1

Additional context
I assume its some sort of name filtering. But should it really kick in on "nepistan"?
The bug is new to game version 0.30, as i used the name without issue in 0.29 and before.
