Not Sure if it is something with my mod or what But for Hyperkillers-Addons, if you try to upgrade a solar panel, it will place it down in a incorrect spot (goes 1 tile down and to the right, for when I tried it) And if something prevents it placement, then it will error and delete the solar panel.
Just found out it does not work well with items that do not have that attribute "fast_replaceable_group" and any items that dont have this will be placed off centered or deleted if it cant place it.
