i brought cashworks down to 98%, when it was above 100%, 32 man servers crashed due to the "no free edicts" error
the error basically means that source can´t handle all the entities in your map
the error gets worse when valve releases new updates, because hats and new weapons also count es such (feel free to correct me if i´m wrong)
try to keep it beneath 100, it might work with more, but let me tell you, it´s a b**** having to cut away details and entites like path_track and such
