[Outdated][Bug 1.15] Some bugs

Just messing around with 1.15 this morning and noticed I could not place front or real axel spots even after I researched them. So I just simply saved the game and reloaded it and it worked fine. But after I reloaded it I could see my parts moving all over the screen but not on my parts conveyor lines. I deleted the parts importers and re placed them and everything went back to normal. But I wasnt paying attention to my money during all of this and went broke. lol
