Yes, it is a glitch. Try to restart the page or the computer.
Tried multiple times
Try to copy everything that you have written, then delete it, save the Episode and then paste the things that you wrote in the Episode.
Hope it made sence
Ok
Let me know if it worked.
Now the system is crashing when i attempt to copy or cut the code
Are you using chrome or safari?
Chrome
It’s definitely a bug in the system, it’s not your computer it’s the site itself. You should send a ticket help and report about the portal bug. It’s honestly your only option.
Okay
I think the background itself is flawed^^ It makes overlays do random stuff and glitches sometimes -happened to both me and ppl i know, and also someone on the forums has also been talking about it. Send the ticket of course, and somehow try to save the script, but if you can try with a different background it might solve itself! I have downloaded my own black bg cause the INT. BLACK - NIGHT keeps glitching. 
it looks cool though
okay but
oh hell naw
Try refreshing, or restarting your computer/laptop (the device you’re using). I dunno, it always helps to find out wether it’s a glitch or a bug.
