can i use this pack for my FM24? is there gonna be a problem or not when i use it because of no 180x180 logos?

Yes but I would suggest download the FM25 version instead. It is a much improved pack and will work perfectly fine with FM23.

can i use it for FM23?  

No, all logos in the 2024.12 file are included in the new Megapack. If members are continuing from their FM24 Megapack and have download all 12 updates they essentially have the same pack. The only difference is we have removed the 180x180 logos. More on that is available in the help section.

i have a question: is there any new logo included in here that wasnt included in the last 24 update? I suppose no but just in case
