Ok I'm going to say right now that this isn't complaint! If it was moderation action I have no problems or gripes at all! But since it could be result of bug I'm reporting it here.

So (about 1 Hr b4 time of this post) there was a thread (I think in general chat but IDK for sure) titled _I don't understand how this circuit works_ (or something vry close to that). So OP asked question that was totally ambiguous cuz he/she didn't provide any context. When responses pointed that out he/she posted image which I couldn't see properly cuz I was browsing as just guest. So when I logged in to see pix and hopefully help him/her out I got message saying something like _requested thread couldn't be found_ and now it's totally disappeared!

So anyhow I just wanted you 2 know in case it wasn't moderation action deleting or moving thread out of public view

For info: the TS started a new Thread about 10mins ago for exactly same topic, deleted the new one.

Update:
It appears a Co_Mod has moved the old Thread from Projects to Homework [ where it should be]
