Diablo 1 HD Hellfire Mod | Awake

Hi all, playing as a necromancer this time. went down to floor 3 and i can see enemies highlighted in red for some reason. i have nothing cast...do i have some sort of perception bonus....like seeing trapped barrels and chests but with enemies. its kinda annoying because i dont know where its coming from. at first i thought it was a texture glitch or something. what is causing it?

SCROLL OF INFRAVISION. or MURKY POOL shrine Casts Infravision (monsters out of visual range gain red overlay)

oh thanks it was probably Murky pool. Havnt had the issue since and touch about every shrine and.
