Max post/spoiler capacity

Well I ran into a hiccup during editing the first post of my massive loli thread
and ran into a problem when adding 4 weeks of pics into a 1 month spoiler like I had done before, thou once I was done preparing I clicked preview and my post was gone, I copied the thread txt, and posted the edit, unfortunately after that my first post vanished nano desu.

I ended up having to split the weeks lolis into 2 batches, but its still bugging me..

So I ask, what is the max capacity/amount of letters 1 post can have, and same for spoilers, did I just overload the spoiler?

Hmm couldn't you have accidently selected all of the text, and deleted it (or have written something, thus deleting what you had selected)? Just a possibility.

no i went back and kept trying with the full text and the new spoiler containing 4 weeks of pics, all properly formatted, and previews and edit button always showed nothing, not untill I broke up the 4 weeks into 2 parts did it work, I believe I over spoiled???? which is y i ask, and with that I wanna know about max post capacity nano desu
