Yesss , thank youuu soooo soo much ! I really appreciate all of your help , for real ! I will definitely get on these issues on my end as well , thank you for checking that .
And no worries , thank you for your work ! It's an awesome plugin :D
Uploaded the new version.
Hopefully it fixes the issue for you.
Also, made a part that should fix save files made with older version. When you try to open such save file, it will load even slower than before. But once loaded, the data will be optimized and map transfer should be smooth, and when you save again, save file size should be normal.
