How do you fix your hammer editor leak?

Answer 1

If you have not run the game that you are making a map for, or if the destination that you are trying to place the final .BSP file in did not exist at the time you attempted to compile your map, this error will occur as a result of Hammer lacking the ability to create file folders. This happens to a variety of people, most often when the person receiving the error has recently rebooted their computer after a crash, their computer dying, or a virus or other possible cause of computer data or memory loss. If this happens, all you have to do is run the game you are making the map for, or simply browse to the closest file directory to the one you are trying to put the final .BSP in , and make a folder named the same as the selected one.
