Factorio 0.18.17
Krastorio 2 0.9.8
Change Map Settings 4.0.0
Squeak Through 1.8.0

When i place red inserters with gaps between, then try to fill the gaps with yellow inserters, the yellow will replace the reds.
I posted this on discord as well, here is a link to the picture i made to help explain:

I confirmed it working as it should in vanilla.

EDIT: Der_failer on discord just tested this. It is working fine for him in 0.9.7, he upgraded to 0.9.8 and behaviour is what i describe.

Strange, I do not have this bug on 9.8

Please let me know if i can help.
I just tried by disabling Change Map Settings 4.0.0 and Squeak Through 1.8.0 and it is still happening, so Krastorio2 is only mod loaded.
Tried in sandbox, in case it was my save. Same issue there.

Вчера тестил, установлен только этот мод, в 0.9.7 было нормально, в 0.9.8 красные инсертеры заменяют желтые и синие и наоборот. На других не тестил.
