I have a problem. I'm trying to make a few edits to gravelpit for a friend, just timer changes some health pack/ammo pack changes, nothing hyper special. However, when I decompiled it, (used both the one on tf2maps and one vmexed myself) it opens with 4 invalid brushes. Hammer then crashes. Resaving it also causes a crash. If I reopen it again after saving, it has 1 invalid brush and the crash occurs again. I can then open it after the 2nd resave, however, all of the entities are gone. There are stll brush entities (triggers areaportals etc) but no lights, models, logic or anything. Opening the entity report gallery has a lot of 'missed' blank spaces. When scrolled down, some of the trigger entities are visible. Does anyone know of a way to fix this, or a ready decompiled working version? PS. This map was previously working before the MvM update, as was the vmf I was using I believe.
