Compiling Server Source on Windows with _IMPROVED_PACKET_ENCRYPTION_

[aw3s0m31416 0]

Hello Folks,

I compiled my Server source code, so it runs on Windows. However, when I try to log in I get stuck on Login. No core is crashing. On rare cases I am able to log into the game. When I remove the _IMPROVED_PACKET_ENCRYPTION_, everything works fine. 

In the syserr.txt in the Client I get: Unknown packet header: x last: 251 250.

My question is: Is this normal behavior, when developing on Windows, that _IMPROVED_PACKET_ENCRYPTION_ isn't working properly? To me it seems Undefined Behavior.

Can you share your experience regarding the _IMPROVED_PACKET_ENCRYPTION_, especially on Windows?

Thanks.
