So I was doing some editing, but when I went to save the mission, I got an error about some sexp expressions (this usually happens when inserting new events between other events). Whenever this happens I just press continue and then proceed to fix them. This time however I got the following error.
Error: Failed attempting to reload mission after saving. Report this bug now!

Every time I try to load the mission in FRED I get a window that says it is unable to load the mission file. How would I go about fixing this?
