I will be updating this post if I encounter more on my next playthroughs. I will also be adding feedback.

THERE WILL BE SPOILERS


- Kain's model looks oily and weird. It would be nice if his textures got tweaked out a bit.

- Dumah gets stuck at the obelisk room during the chase sequence.

- The Ruined City unlockable count in the map does not register properly, getting stuck at 0/1 life upgrade pieces even after acquiring it.

- There is a very rare bug at the bonfire room at the Razielim territory near the door to the warp gate. When you come back to this area from the door at the opposite side of the warp portal, the map will not load, leaving Raziel in an empty void. This can be fixed by crossing the door once again, and this might be an error from the original version of the game, since I can recall this happening in it too.

- Sometimes, the Rahabim’s projectiles cannot be deflected by TK, although I just encountered this issue once.

- The bars at the lower level of the area when you first encounter the hooded wraiths cannot be phased through in the spirit realm.

- The first human you ever come across is completely indifferent to Raziel's presence [It seems that some devs want to keep it that way. Please don't, honor the original game, fix the bug.]

- There was a single instance in which I started one of the Lost Levels and the game started a New Game for SR1 instead of opening the Lost Level. This just happened once and never again in several sessions.

- The achievement "You Are Persistent, Raziel" cannot be unlocked by comming back to Dumah. I discovered this on the PS5 version and I'm not sure if this is the case on PC. So far this is the only boss that I'm aware of that has this problem. Please mention in the comments if you had a similar issue with him or other enemies.


- During the first in-game cutscene, when Moebius shows Raziel a vision of Kain at the Pillars, old graphics are used. You can easily notice that the old Kain model is in display on new graphics mode.

- The PS2 blurry effect when Raziel finds the physical Reaver is missing.

- The texture of the reflecting panels in the Dark Forge look really bad.

- There are giant black boxes on top of the mummies at the Air Forge.

- The music volume is too high during the final act, when Raziel makes his final travel through time.

- Human Raziel's new model's face looks weird and oily. Also, he keeps his eyes open when he's dead, in the original graphics, he has them closed.

- Moebius does look very oily too, I would love it if they tweaked it a little.

- Kain still looks oily in this one.

- The Sarafan Priestess looks weird and less detailed compared to the other human enemies.

- Some subtitles across the game go very fast, and sometimes they don't show up.

- Fade outs do not work properly, as effects such as light sources and particles are still visible through them. This happens during cutscene transitions or cutscene skips.

- The Scare the Crows! achievement might be a bit buggy. I tried in my two playthroughs of the game to scare every single crow in the eay to the forge and it did not trigger. It seems that a popular YouTuber specialized in guides posted a workaround in which you have to save in the sorrounding area and then try again. The author of that post is PowerPyx.

- The spectral world version of the cutscene that happens right after the fist Kain meeting cannot be skiped, the physical world one can, though.

If you find anything else, please add it in the comments.
