incomplete tiles retrieval in zoom=5

[cesarbenjamindotnet]

hello, please let me congrat for your amazing lib.

but i had some issues i guess, while i tried to get an equirectangular photo of zoom size of 5, i got an incomplete one, i tried many times and all of them i got the final image incomplete, and the missing parts are always in same location.

i did upload a screenshot of how it looks. When i did the same with zoom=4, the image is complete.

Can you tell me something about it? in the JS console i see the event progress gets complete, and the complete event is called right. whats the matter here?
