Hello!
I've found a bug that occurs when you have multiple lists of elements in the text, and you change the text type to "body" while multiple lists are selected. All lists get merged into a single list, placed one after another starting at the position of the first list.
Example:

When all text is selected and changed into "Body", the output is:

(another bug: numbers in a numbered list always get converted into 1s when a list is converted to "Body")
Now, this doesn't always happen. If you just write random paragraphs and lists, things might work as expected. I suspect the bug is due to some markup present in the above example, but haven't figured out the exact cause yet. Also, it doesn't seem to happen when you change to other types than Body.
Below is an example of markup (saved by Writty) on which the bug does occur. Change the file back to .html and open it in Writty.
