Please DO NOT download ETlegacy 2.76 as it will not work on any servers using pk3 as menu of char ~~ or Ext ASCII characters. Matter of times server admins start spamming zzzzz in pk3 names. I have no idea what is the logic behind blocking pk3 file name rather then blocking menu override itself.
I have tried to talk with @kemon , IRATA and other member of Legacy team. They went out with this approach which really doesn't make any sense. Let's be honest here - it doesn't - no matter how much anyone tries to justify it. Even @kemon you and IRATA both even agreed to that i.e. blocking file characters is not a good logic, in our conversations so i have no idea what happened during release.
Here is prime example - Gun control is an issue for massive crime so some people decided to block ONLY SMG's but rest of the guns would be still freely available in market. Does that make any sense? Because you ban SMG but rifles, other guns, pistol, etc etc are still available in market.
So same happened in ETLegacy 2.76 version. They just banned 2-3 characters in ETLegacy version. Matter of time admins will start spamming pk3's with name zzzzzzzz, yyyyyyyyy, xxxxxxxxxx - etc... etc.
I have no idea what else to say. I have tried to convey the message since months to the team but they did - what they wanted to do it even though few members had told me that in next version they will not block any file names. No offense intended to anyone. In my book - it's horrible logic. It really is.
