Unknownreported this bug
hello, use this as an example
/mm test mechanic - potion{type=DARKNESS;duration=200;level=4;force=false} @self
spam it a bit and you will see that the potion effect will get refreshed (re-applied) even tho force=false
quoting the wiki this is not intended
Whether not to override the current potion effect or not.
it should not force if force is false
