Weird lines appear when exporting to png
Hi,
When i export my illustration to png (i chose 300ppi high resolution), weird lines appear.
This is what it should look like:

and this is what it looks like once exported:

i think it might have something to do with the gradients that are applied but i have no idea how to fix it.
The artboard is 961,8029 in w and 560,7211 px in h, i need a smaller artboard, but when i do this, it loses quality and i get the same problem with the lines.
please help.
