First. the emissive 2x1 slope base panel and its inverted form have different names. One is ": "LG_Emissive2x1SlopedSideBasePanel". And the inverted one is : "LG_Emissive2x1SlopeSideBasePanelInv". Small but confusing difference.

Secondly. One of the bases, I believe the LG_Emissive2x1SlopeSideBasePanelInv, crashes users games when pulled out for placing. I've been trying to do some debugging on my own to fix this, but I do not know enough about modding to update the code that is causing it.What I believe to be the relevant part of the log is below:
