Interesting Discovery with Conveyor Belt NPCs

[MacheTheFerret]

I was testing something earlier today with conveyor belts. I added these NPC codes to the npc:

playerblock=1
npcblock=1
grabside=1

I was attempting to make them grabable and movable. Picking them up worked, but madness ensued after I let go of the conveyor belt.
The conveyor belt teleported to it's original location.
Not only that, but then on, NPC's phased through the conveyor belt.
And not only THAT, but for some reason, if there were no blocks right beside the conveyor belt, Mario would automatically jump at the end of the conveyor belt.
And not only THAT, but for some reason, if the conveyor belt was place directly against a wall and it faced the wall, and if Mario were to stand right against said wall, Mario would not be able to jump at all.

I don't know what to make of this or how to utilize any of the glitches. What do you guys think?

Maybe this could be used for a mechanic that doesn't allow you to drop an item you're holding?

Not only that, but then on, NPC's phased through the conveyor belt.

Do you mean it lost its ability to hold other NPCs on top of it, or something else?

And not only THAT, but for some reason, if there were no blocks right beside the conveyor belt, Mario would automatically jump at the end of the conveyor belt.

... Wallkicking?

And not only THAT, but for some reason, if the conveyor belt was place directly against a wall and it faced the wall, and if Mario were to stand right against said wall, Mario would not be able to jump at all.

This part... I have no idea what that could be used for. Captain Toad levels, maybe? Even then, I'm pretty sure you could just input something into LunaDLL and make it work that way.

But if the only NPC that does this is the conveyor belt (as far as my knowledge goes), what would be the point?

It lost it's abilities to hold NPCs on top of it.

Wouldn't that require you to pick up the block first?

That part would probably be annoying should grabable conveyor belts blocks become a thing.
