So my map I was working on had a Invalid solids error and deleted everything. Well luckily I have a exact copy of that map with everything still in it, only problem is: When I open it I get the prompt to remove solids. I know what the solid is: Some block that has no properties(aside from being visible) thats Where I never placed a block. Now I wanted to know if there is a way to access auto-saves so I can just go to the last autosaved file and try to work from there. I really dont want to have to re-insert the props, (they took me like an hour to place). I read somewhere on the forums that this has happened to other people and one way to work around it is to find an autosave in Hammer Editor and work around it. I would really appreciate some help on this subject. Also sorry if this is not the forum where this goes. Didn't see a "Help Desk" so I thought this would be the best place to post this. EDIT: Also on a side note I dont know why this is happening but water is invisible on the surface in my maps, I made the water correctly, (Using nodraw on all sides but the surface) and I have a water lod control and a cubemap nearby in a building, my map also has no leaks. Its just a small puddle but I would still like to see my water. Any way to fix this?
