This is a regarding the respawn of dwarven ghouls. It appears they respawn quite fast and many times come in pairs of more than 2 to 3 times with spawn interval of few seconds. This has been happening from past few updates.
This is the only enemy I find the respawn rate quite fast compared to others.
I request the developer to please reduce the pairs spawning on the floor with some cap on their respawn timings.
Per my other comment, I noticed this, too. It seems to come in waves rather than being consistent.
