I'll start;

my issue was when I used it, and hit space, it'd make me go upwards for a second or two consistently, and I couldn't figure out why it wasn't my movement mod(I disabled it even in game through it's options) and I don't have any other movement mods, it would just be when I "yesclip", most of time(sometimes inconsistently), if I pressed space to go up straight, it would act if I held it exactly for a specific amount of time, like one or so seconds.
