As part of today’s patch, the much anticipated multibuy feature was introduced. This feature allowed players to purchases multiple items from the in-game market from pre-saved ship fittings. This feature would reduce the tedium of buying the fittings for a large number of ships, especially for players who buy in bulk.
The feature had some issues this morning and had to be temporarily disabled. While the issue was quickly resolved it will remain disabled until downtime tomorrow (Wednesday 30th).
