Yeahhh that's the thing - I may have dawdled prior to saving after seeing the signal because it caught me by surprise, and only after I had three separate friends go "the consequences!!!" did I try to wipe it. And I did try, but I think I dawdled too long, because I tried speed-running the process (wipe signal on PC, remove signal from tape, smash tape to pieces, turn off all the power, put PC into 43-foot hole in ground, bury under rocks and boulders etc etc) but I never got the follow-up saying "gj bud". My main suggestion I guess would be to give that an event flag so you can't pause or save after processing the signal, same as with the other spooky moments.
