Hey,

If you swap an offline version to live there are some issues with the mm relations.

It tries to update MM Relations in the Datahandler like this:

function: version_remapMMForVersionSwap_execSwap

        if (is_array($this->version_remapMMForVersionSwap_reg[$id])) {
            foreach ($this->version_remapMMForVersionSwap_reg[$id] as $field => $str) {
                $str[0]->remapMM($str[1], $id, -$id, $str[2]);
            }
        }

However the id's are not "negative" anymore for authored entries. Instead it uses the actual ID's of the related entry.

I tried to switch the "-$id" with a "$swapId" but that then leads to a unique error since the mm table should only contain each relation once.
I think it might would help to add a new small function that compares existing entries first before trying to re-apply them but this would probably lead to another issue (cause the entry for the swap ID also exists).
