I am playing a custom modpack (modlist https://pastebin.com/J0JjpDsS) and for some reason the tutorial Add Velocity spell is only working when I cast it downwards (not necessarily straight down), with no effect at all when facing up (even tried in creative). Additionally, it seems the spells takes 0.5-1 seconds to take effect, even when it works, even if the server is running at 20 tps. Is this known?
