Hi again BreBre,
They completely changed the beacon animation code in 0.18.32. Instead of rewriting my code to disable the new style of beacon animations, I just deleted it. So beacon animations are no longer disabled. This is because the current beacon animations (just a little puff that goes up) is much less intrusive and I don't really think disabling it is necessary anymore (vs the old spinning beacons which had more of a belt-like effect).
Thanks for the report. Please update to 0.0.5 and enjoy! This mod now just disables belt animations.
