Unknown verb form (typo?) in manga


I've been trying to translate Touhou _doujinshi_ , when I came across this
sentence:

[![a man talks about youkai's
den](https://i.stack.imgur.com/dJLIN.png)](https://i.stack.imgur.com/dJLIN.png)

A man talks about events related to youkai's den down the road.

The first part of the sentence is:

> なんでも綺麗【きれい】な女【おんな】がたくさん出【で】てきて呑【の】めや歌【うた】えの大【だい】宴会【えんかい】

Meaning, I suppose, something like:

> “Lots of different beautiful women come out and have a big feast where they
> drink and sing”

And the second part is:

> でもあくる朝【あさ】には肥【こえ】だめに **浸【つ】からされてたって** よ

I don't get this 「浸からされてたって」 part at all. I thought, that maybe there was a
typo, and it should be 「浸かられてた って」. But, as far as I know, English translation
for 「浸かる」 is already in passive voice: _to be submerged; to be soaked_.

What is the meaning of 「浸からされてたって」?




漬からされてた＝漬からされていた＝漬からせられていた

Verbs often have two causatives, one in ～す and one in ～せる. ～す is considered
more informal these days, but I think it's the original. So this is the past
of the passive causative form.

'has been caused to be submerged,' literally
