Cohadar once said something (within the first two pages of the TT thread off memory) about evaluating return-nothing boolexprs causing desynchs. So unless that is tested I don't consider it safe.
Then again, return-nothing and null are two different things. So I suppose it may be fine. I'd still want to see it tested, though.
(Obviously people do null boolexprs all the time. Problem is in evaluating a destroyed boolexpr, that handle may be reused, and you may try to evaluate a unit or something dumb or a newer boolexpr, which may execute code you didn't want to execute.)
Hmm, about the Headline News, I noticed threads are being moved into the subforum (Health News, Environmental News, etc.). When that happens, the TH Forum Home page loses the articles, and instead would show old articles posted 1 or 2 weeks ago.
Question: Is there a way to remove thread redirects? It creates a copy of the moved thread and takes up space, and I am leaning towards wanting to remove them in the Headline News. But if they have an expiration date, I guess I'm fine with it.
if a redirect ends up in the same forum as the post it goes to though I think the redirect drops or fails or something but they are not bugged out and when you are working on an indirect the original post is safe.
