It is likely the crash is happening is a result of the loop script trying to load a quick save, I didn't think about having the level quick save before loading.
there is definitely a loop script in order for the leveling system to work in the game and to keep track of experience,levels and scrap.
Also on adding way more to the enemy animations, I don't think it will be possible, I had difficulty drawing the current ones, adding more frames is likely to make the enemy animation even worst.
It makes me wonder if your monitor is going black due to me using Alpha 54, I am not sure if the other games you played had a newer or older version of EFPSE
