are you sure that you removed the mods you thought that they were responsible for the issue, correctly? if you only deactived the .esp 's from the load order, read this: only deactivating the .esp from the load order will not fully remove the mod. to fully remove the mod, you need to actually remove all the files that came with it. to do so, its best if you see your mod download, and what it contains, search for it in your oblivion files and delete them. note: maybe there were some things replaced, like textures. if u are unsure, dont delete the files, but copy them to a safe place out of the oblivion folder, so in case things go wrong you can put them back! (i personally always back files up that are going to be overwritten in a mod installation process, so nothing can get messed up.) if not, continue here: your mods seem to be okay otherwise. except for one thing about the load order: why is oblivion.esm not at the very top? if im not wrong it should be first. anyway, try running BOSS (better oblivion sorting software) you can find it easy here on nexus. another thing you can try (most likely wont help but try anyway) load another savegames and see if you still run into the same problem. oh and try disabling this: EVE_ShiveringIslesEasterEggs.esp idk what it does but try anyway. another thing that comes to my mind is: load an older savegame and try starting the quest u wanted to play again, and see if the same problem occurs again. post your results good luck!
