I only use URM in this for testing purposes, but it has never caused an issue for me. I suggest making sure you have the latest version of URM and removing both persistent files. Then a fresh install of the full Ep14 version. Bob's compressed version is only 1.2 gig, so it doesn't take long to download.
Yes, the word from Dima is that the Leelee date is about 2 or 3
Weeks from release. That's just enough time to make sure Ep 14 is perfect before the full court press to the finish of Chapter 1.
Not the compressed version hehe this game is good enough for me to play it the non compressed version, tier A for me near tier S and maybe reach there with the improvements. Only tier B and C games in my own rating I play them compressed if they are too large of an install for their overall quality

.
I'm just using the update only files for some updates so that maybe left some file or code from previous builds that is giving incompatibility to run along URM but in the actual gameplaying it never gave me any error (and yes I have always a copy of the last update of URM to spread along renpy games haha), its not a problem, this game doesn't really need guidance, I'm just always curious on what is under the hood of the games hehe that is why I usually use URM.
Yes on the next update I'll download the full game and make a fresh reinstall and then I apply URM and will make a fresh playthrough anyway, want to check the improvements on previous episodes and is about time to make a refresh of the full story so far. But since I have other games to play that will last that 2-3 weeks time frame or even more I prefer to wait next update and play it with the addition of more new content.
The only time I have had a problem with URM was when I was also using the gallery mod. Tossed out gallery mod & URM worked perfect!
Not sure what your issue is - have you posted it on URM thread? Maybe they know something. Good luck!
Hmmm maybe that is it, yep have the gallery mod applied, I'll try to move it and see. Thanks for the hint.
Edit: Actually it isn't the gallery mod the issue, works fine with URM along with it. The problem was the denoiser mod, forgot they were incompatible, I knew this before, just my memory sucks sometimes. Actually gonna toss that denoiser since the game went into improvements anyway and I guess making the images and animations smoother and less "noisy" was one of them haha.
