There seems to be a bug with the autoplacement when the entity has a very small cbox.
Ive tested this with an inserter because they have a handy direction indicator.
Setting it up like this
insert_pipe_connection(pipe_connections, prot, {x= x, y=y+2}, new_connections)
results in a connection facing to the north / pickup direction. When adding another connection at
{x= x, y=y-2}
it will be set to the east(?) instead of set it to the opposing / dropoff side.
Now let's use
{x=-x, y=y-2}
instead. Expected here is that it will set the output to the west which it does correctly.
{x=-x, y=y+2} should set south-east but both outputs now face north.
It seems that keeping y-2 lets me set the x position correctly while y+2 is a bit wonky.
Possible fix:
When a cbox is smaller than 1 just do y-1 before applying the insert logic. This won't fix anything at all but its output more reliable.
Like setting {x= x, y=y+1}
and then use {x=-x, y=y+1} or {x=-x, y=y-1} will result in the same output.
Also the second connection must have a negative x or it won't be set at all.
