Yes, having not done so yet, I too would like to express my thanks to all who have taken the time to improve such an old (but still great) game and give it the proper completion it deserves. All of you deserve recognition for your part in seeing this come to pass.
Now, it is my understanding that this is the second attempt from this group to make USM and TSLRCM compatible. The second go around it was supposed to have been tested. Are the modders aware of this issue? Is there any investigation/work being done to fix this?
I am not trying to be disrespectful in any way here. However, since this is a gamebreaker (one that seems to be at least a few months old, mind you), I would think it would at least garner attention from those who can do something about it. As far as I can tell from scanning the thread (and I could very well be mistaken here), it has produced zero responses from any such person. Do you need some sort of savegame to work off of or something? We could all obviously oblige. Either way, please at least acknowledge that some sort of progress is at least being attempted.
Thanks from all of us :-)
EDIT: So I did a search with black screen on Malachor (or somesuch as keywords) which pulled up 6 threads here discussing this same issue. All posts there operate on the assumption that this is a TSLRCM/USM compatibility problem. However, they were all dated before the "working" compatibility patch was released for versions 1.6 and up.
In one of those posts, they say that it has to do with the fact the old patch didn't work (the one designated for TSLRCM v. 1.5). This implies that they at least knew of the issue then and intended to fix it for TSLRCM v. 1.6 and up. Obviously, such is not the case. At the link below, zbyl2 says to remove k_907_mal.ncs from the override folder as a possible workaround. Stoney also suggest downloading a file and then removing a file from the override directory. I'm not sure if all these fixes are supposed to be used in conjunction, separately, or both (depending on the case) nor is it clear if anyone actually got them to work. I would imagine you would have to have a save game available before any Malachor modules load up (up to just before you leave the Ravager and save Telos) in order to properly try it out. I won't have the time to try it for at least a few days so if anyone else wants to give it a go, let us know how it turns out.

EDIT 2: In another place a poster had a similar problem where they actually proceeded normally to the point where they enter the Trayus academy and were then sucked into the black hole from whence there is no return. There, zbyl2 suggests removing k_907_enter.ncs from the override directory as a workaround and that person got it to work, apparently.
