I have to say OpenMW is more stable than any other MW I've modded before. And last but not least, just googling, reddit, and abot's pages in general have always helped me pick my way through the thorny path that is modding Morrowind in any form. Another big help was the timely release of the non-openMW 2019 pastebin guide by Thastus.

Second of all, the next best resources I found were on OpenMW wiki pages, particularly the list of catologued mods that work, as well as Darklocq's list of mods in testing. First of all, I have to say, this guide was exceedingly helpful, I used the 'total overhaul' option as a baseline for modding my game. I spent about a week building this, and it was my first experience with OpenMW.
