I decided to go to Umbra and get the sword at level 2 to finish the Clavicus Vile quest early. Whenever I am in the Vindasel catacomb and find Umbra, the game crashes and very frequently. I have 3 quest related followers, plus 4 scamps and it doesn't matter if I tell them to wait outside or bring them with. I coc'd to the testing hall and took Umbra from there; I gave Umbra to Clavicus Vile and finished the quest. However I would rather finish this without going to the testing hall. If anyone could tell me why this is happening, it would be much appreciated.
