Alright, I have worked hard on my first map and I havent had any leaks for a while (Since I fixed them all). Today I was pretty much finishing my map; putting func_nobuild in spawns etc. I had compiled the map multiple times before I got the leak. (I pretty much did 1-5 changes every time before compiling the map). But suddenly when I tried to compile (with VBCT), I got a message that I have a leak. I loaded the pointfile, and saw this red line starting from the center of a prop (a barrel), continuing through the floor and ending somewhere in the void. I hadnt done any changes to that area for a while, and Im pretty sure that its not a "regular" leak. (I tried to seal the area where the leak was without any luck). Im pretty sure that I had just modified my func_brushes to make them fit better in my lamp (with the Vertex tool). I tried to google my problem and I found out that origin helpers can cause leaks, so could it be that my func_brushes origins are a part of this mess? I tried to center them to the enteties, but it didnt remove the leak. (EDIT: I have also tried to remove those func_brushes and that barrel which was in the end of the red line) Dont know if these will help: Hopefully someone can help. Thanks.
