This is latest pre-"NPC fps_max fix" version of the server DLL grabbed from an official Steam depot + the client DLL from the same version.

Install by replacing both bshift.dll in dlls/ and client.so in cl_dll in steamapps/common/Half-Life/bshift/ (backup your original ones!)

See here for the issue: https://github.com/ValveSoftware/halflife/issues/2458
