I have been working on a map for a few days and it has about 240 territories for now and file size was about 1.60 MB but now I just made 10 territories, simplified them and when I tried to upload the map it said file was too large with 2.30 MB, why are they so huge? i have made bigger, smaller or more detailed territories and I just got this problem with these average territories. What happened?

Need more information. Create download link for file and share it. I should be able to find the problem if i can see it.
