V 17 is an old version, like an old car from '50 years. Since v17 eve evolved, made-it more difficult and more complex to dig-in . More than that, eve start to make really often changes and his events influence entire game interface and play
that’s why v17 evolved at v18, a version adapted a this changes. ANd Viir prepare an even more adapted version , to keep-up pace with this changes.

Now back on v17; to make this version to work you have to adapt all changes( maybe half of sanderling) since then at this version and, some of them cannot be adapted( or the cost is too big to make them). Hope is good, if is anchored in reality; if not … it transform in a dream
