Hmm, I never use megainstallations and BP-BGT Worldmap, but perhaps that's an installation order? Perhaps BP-BGT Worldmap should be first and then those mods.
This specific component that deals with icons was designed by K4thos, but he's been away for a while. Someone who could find out what the problem may be is Gwendolyne but I'm not sure if he has time. Eh... not sure what else to tell you right now. I will see if K4thos may be reached or let's see if Gwen comes here. Meanwhile, I would suggest changing checking if the installation order may be changed. It kinda looks as if the mods tried to update a file that does not exist in your installation.
EDIT: And maybe CamDawg will know what the problem might be?
