Missing Meshes

Hey Im new here and I love Oblivion and Morrowind and Morroblivion is probably the best thing so far thanks! I'm familier with modding and construction sets... anyway to the point! Some meshes are missing and I understand that it might be the conversion problem Im just wondering if there is a fix or anyone is experiencing the same problem... In Dwemer Ruins, some activators and meshes seem to be missing.... A big downer is when a hallway mesh goes missing (you know exclaimation mark in a triangle), its the one where you look below and there's lava... Lava does no damage though im aware it has something to do with "water" right? Smokes and steam from Dwemer ruins are missing.... To Compensate this I actually modified by replacing them with other meshes or just removed them (For Dwemer ruins I just replaced the hallways missing) Please let me know if theres a mod that fixes it or if anyone is having the same meshes missing OH and im glad to be here by the way i hope to contribute for the good one way or another :) Didact1
