Hello there, I recently installed Morroblivion v50 and tested everything and it all works so far apart from one encountered issue. Just outside of Seyda Neen, across the bridge, when I turn right to go to the Adrano Ancestral Tomb I CTD next the tree on the right.
The tree in this image, on the left of my cursor. To the left of where I stand is the Siltstrider.
Here is a picture of my load order, although I doubt this is caused by a mod conflict... best to provide as much as I can.
Any help would make me greatful. I can walk around the spot from other directions, so it seems to be affecting only one or a few cells in that small area.
Edit: Resized images so they could be veiwed better, possibly. If you'd like a better veiw of them, let me know and I can provide links.

There are a lot of CTD issues, due mainly to Oblivion's engine's limitations. You can try any of the various stability improvements on TESNexus, listed here.
