@vagueGM In fairness, it's not EXACTLY a regex problem, but kinda a processing one. Last time I tried fixing some of the nesting bugs, things exploded.
For the moment, try not to mix up the nesting of ooc and spoilers. I can see an easy fix for this which I'll look at getting coded up.
When the enduser is allowed coding, they will introduce bugs. If you can see an easy fix that prevent the lockdown of a tread, go ahead please. But if you are thinking that you should correct the endusers code, please don't. That is a rabbit hole of userfuckups that you will never be able to handle.
