Thread continued from discord at the suggestion of IchoTolot:
In neolemmix, the 'owa_down' object from 'orig_fire' contains an animation error:

The current animation is on the left, the fixed version is on the right.
This inconsistency is not present on the left/right one-way-arrows.
Only the graphics contains an error, the .nxmo file seems to already work as intended.
Attached is a graphical fix which updates the down-facing arrows to be more like the left/right arrows, as seen in the above gif.
Thanks Dex. I've added this to the styles included with CE. For regular NeoLemmix, this will need to be added to the style manager.
