Yeah that's been a problem that I've been trying to fix for a while now (well tbh more like, wanting to fix it but dreading having to basically redo the scoring code so I kept putting it off lol), but I finally fixed it last week! It's consistent now in my dev build (apart from very very slight inconstancies that I'm pretty sure are just floating point imprecision, they're way too small to affect the score since it's shown as an integer in-game anyway, so it's basically negligible). It'll be in the next update, which will also have some other stuff like all Ch4 maps!
