I have made a quick fix. It is a very small fix but it makes all the robotic parts show up in the Ground category. and every thing then works for me.
first install Rework_Repack_1.1.2
Delete GameData\MagicSmokeIndustries\IRActiveStruts folder and GameData\MagicSmokeIndustries\Parts\Rework_Utility\Probe\Struts folder
Then install my Rework_Repack_1.1.2 fix and merge all folders and over right all files
