Okay I got the suitcase analogy ahah anyway as you said I don't think I need to put other stuff in my map. I tried the first two steps of your guide but instead of 1.94MB that you obtained, my file reaches only 2.28MB. I read multiple times your explanation and I think to have followed all what you said, I don't understand what's wrong whit it :(

Strange! I'll send you my version later today so you can compare.

Thanks, in the meanwhile I'll try something else

if you're map is too large try https://jakearchibald.github.io/svgomg/

I see someone already posted the link oh well

Looking good! Glad to see it all worked out!

Woohoo, congrats!
