I would say, just in case you saved the signal to your computer, make sure you go in and delete the saved signal, too. If that doesn't work, try reporting the bug to the bug report thread.
Where is it exactly?
If you've saved the signal, it'll be in your Database on the computer.
Uhhh, sorry, i mean where i can report a bug?
Oh. It's a pinned thread at the top of the forums. There should be one dedicated to 0.7.0 bug reports.
Okay thx very much, but what can i do now? How to get rid of this signal? I want to continue playthrough...
Have you tried looking in your Database?
Yeah, i even saved it by myself and deleted it, just to try.
And even with it gone from your computer, the event is still killing you?
Exactly.
