Missing RecvProp for DT_BaseGrenade ?

[andy1318]

Hi everyone, I created a new mod a few weeks ago and I compiled it, debugged etc and it all went fine. The game also starts up fine but when I try to create a server on a map it loads the map, and than immediately exits to the main menu and I get this error in the console:
Missing RecvProp for DT_BaseGrenade - DT_BaseFlex/baseclass
Ca anyone help me out?
