History not correctly maintained / document not correctly saved

[luckyhandler]

I experienced the following behaviour:

• I create a document (v1),
• add content (v2),
• invite someone,
• delete content (v3).

As soon as the invited person joins the document shows again the old content (v2).

Also, when going back to an older version in the versions section the current content of the file was not restorable any more.

Could this be related to the versions app?
