The Baltic theater has 16359 object(ives) and has long loading times. In comparison, the stock Korea has 2693 object(ives). So Baltic has over 6 times more.
The loading times will suffer at certain points like you describe.
If you read the information put out by TomCatz and it’s also stated in the package of the old version Ostsee, it’s a technology test theater by him.
Really not much you can do about it.
