I had/have the same problem - not because i forgot to repair them or droped them, but something has corruptet my charactor/savegame.
If i load before these 3 quests events there is no problem and sigil stoneitems do not disapeer:
Vahtacen's secret - completed
Lone wandrerer - completed
Enter the eliminator - Acepted the quest

After this any new sigilstone enhanced item will disapeer after closing and opening and loading the game.

To fix this i tryed with out success reinstalling the game [oblivion + shiviring isles], format c:and reinstall windows + oblivion, but this did not fix the problem

If anyone can help please let me know

Tomorrow i will look further into this and see which one of thise missions makes this anoing bug appear.
