ive read there is a glitch on shyrim elder scrolls that u cant locate aldis to speak about a daughter of some woman as a quest, ive located him with the arrow from compass bar but he isnt there looking like hes under the ground any ideas ive tried to to wait for day light as hes been spotted on the courtyard that doesnt work when ive tried it solutions welcome

Leave the area for thirty+ days and wait for the cell to reset.
Then see if he has spawned correctly.
Good luck.
