Train Shape Loader screen blinks?

Attached shows what I mean.
I am inputting on all inputs, on all 3 levels, on this space belt to this train loader. Before I added this second loader, the first one was loading all 3 at once. I can't tell if they're like, consolidating the input into one block? Looks more like it's just deleting and losing shapes persistently.

Game version 0.7.7 (btw, you should make this visible from Settings so I don't have to go back to main menu to check)

you're inputting shapes of different rotations. they're deleting themselves because train loaders can only take 1 type of shape per floor

this is why the left one is stable

Oohhh, shit I didn't notice that mistake.
Although, given the game teaches you the vortex doesn't care about rotation, that also kinda gave me the impression rotation in general didn't matter except for factories. It'd be nice if the loading things could correct for that.
