In the server, ships are currently buy with blocks. I can understand the intentions behind this, as to remove people trying to take advantage of credit farming. However, it takes FOREVER to constantly look at a blueprint, find the next block, find a shop (or person) with those in stock, then fill it out and go to the next block type. Most blueprints have upwards of dozens of these block types, and it could take hours to get 1 ship/station out of a blueprint. My suggestion is this:
Make blueprints buy with credits, but make them more expensive than it would regularly be. This discourages people from credit farming, as it would take a whole lot more effort to get the amount of credits needed to do so than to just make blocks yourself. It would make it easier for starting players, and for everyone who needs that extra bit of support towards making their own factories. I know this can be done withing the server config file, as I have made sure this is doable before suggesting. Please consider this, as it takes so long for blueprints to be filled out currently.
