Hello devs, I know you're already working on this bug atm, I read your tweet (X lel) and I told myself maybe my experience might help you out:

So, I noticed this problem happens with a character I played on the 1.22 experimental, on the DE 3536 1PP, and this character was still alive after the 1.23 EXP release. I have been able to play since 1.23 for some hours, in two different days, but it is really hard to connect to this server. On the first day, I tried to connect with another character I created after the 1.23 release before trying to connect with my first character, it worked! On the second day, this way didn't work anymore, so I tried to spam connection, and it worked! But now I can't connect anymore to DE 3536 anyways.

I decided to test the other character I created after the 1.23 release on EXP, on other servers to see what happens:

• This character is able to connect on different servers very very often compared to my first character.
• Sometimes (very rare), I also experience the rejecting connection problem, but it is solved after spamming.
• Some servers will reject connection everytime.

I hope this can be helpful in some way.

I wish you good luck on this issue, btw the 1.23 is really pleasant. that skybox is really awesome, and so are the new sounds and the new NWAF. Love you guys!
