It seriously sounds like you have a hoarding problem. And as per Sandro's comments on module storage, it's pretty clear there is no role in the game for which you are supposed to need to store this many modules. Buy one ship, equip it, if you need to fulfil a different role buy a second ship and equip it accordingly again.
And before I hear about "the grind", you don't need grade 5 modules of all your ships. In fact you don't even need engineered modules on any ship.
No, no hoarding at all. All i am trying to do is often suggested "get things along the way, do not search for them specifically" with mats/data, and limits here make it completely impossible. As i simply cannot pick up what i find along the way, i have to leave it, and then to search for it when needed. Which is stupid TBH.
Second part - modules. Just an example - the last thing i did - a little bit of experimentation with weapons on vulture. It is the easiest ship in this regard, as it has only 2 weapons, and i never cared about different rolls, which is not the best thing to do, but with this limit storing different rolls is plain and simple impossible, so... how many different upgrade/special combinations are there? I've filled at least 50% of this storage with
completely different C3 weapons. Then, ideally i also needed few different powerplants to be able to adapt them a bit to weapon/shield configuration, a couple of shield gens (biweave/normal/prismatic HD/thermal) and a set of different shield boosters to come with them. A couple of different lightweight utilities so that i an use them when i want 2 chaff for certain config instead of HSL+chaff and such. A couple of different HRP-s + different bulkheads to come with them. And here i am, running out of module storage for experiments with a single small ship... and this is something that actually happened, not a theoretical example for forums. And what if i wanted to do the same thing with bigger ship, with more different hardpoints? Or would you say i should not play the game/experiment with things in practice and use coriolis instead? Or should i sell things and re-engineer them each time i change something?
And what purpose does this limit even has, apart from making me sell and then redo things i already have?
