writer - saving as doc-document - deletes any hyperlinks i insert in the text?
how do i prevent that?
it happens with hyperlinks starting with www. and with http.

it appears not to have happened a few times, now it happens all the time.

Insert > Hyperlink > Internet. Now insert the link. It works when saving as a .odt or a .doc.

Never save files as .doc files

Always save files as .odt files - see [Tutorial] Differences between MS Word (eg .doc and .docx) and LO files (eg .odt) for the reasons.

To be specific: always save as the native OpenDocument Format specific to the used module, then save in whatever other format you please.

Also, the following is relevant about incompatibilities between .odt and .docx files : https://forum.openoffice.org/en/forum/viewtopic.php?f=71&t=83694
