I am unsure if this is a issue on my end or with the master file, but the exterior lava in V55 still appears to be the old styled lava, as opposed to the new flowing lava created by Qwertyasdfgh (http://morroblivion.com/forums/morroblivion/mods/2559). This lava should have been merged with V54, but it doesnt seem to be working.
At the moment i only have installed:
- Unofficial Oblivion Patch
- OBSE v0020
- Elys silent voice
- Morroblivion Master V55
- Thermador's Complete Installation V55
I even tried downloading the Morroblivion Additional Support Files 2, as mentioned in the master file thread, to see if that would make a difference, but it has not.
Fortunatly, i had an older version of Qwertyasdfgh's lava mod stored on my HDD to demonstate a comparison of the lava i currently have with V55, when comapred to Qwertyasdfgh's mod.
These pictures were taken outside Galom Daeus.
The lava with morroblivion master V55 and Thermador's Complete Installation V55:
Lava, as it should appear (taken with an older version of Qwertyasdfgh's lava mod):

I've found the cause of this issue, it appears that both the current "Morroblivion Additional Support Files 2" and Thermador's "Morroblivion Complete Installation v055" have a meshes folder which contains Qwerty's lava mod incorrectly placed within the current meshes folder (so when installed, the path for the files related to Qwerty's lava mod is "Oblivion/Data/Meshes/Meshes").
This incorrectly placed meshes folder should have been instead merged with the bigger meshes folder.
To resolve this issue, the "meshes" folder that was incorrectly placed within the bigger "meshes" folder should be cut, and the two folders merged together.
Fixed in v056!
