Okay so others will tell you the parts of modding in terms of code and resources to make mods.
Make sure though that you have a PLAN of EXACTLY what you want to do before you start doing anything on a computer. Take it from an ex-programmer, if you don't have some sort of plan down before you start, you're just throwing stuff at a wall to see what sticks and it falls apart.
As for items, make sure you make a list of all the stats, perks affecting it, crafting, where it is in the world, loot tables and sprites. If this is all or mostly planned, you won't miss out on it later.
A quick follow up, I seem to have fixed it by giving the JavaVM a ton more memory to allocate (long story short, starting it with the xmx parameter set to 4GB fixed it, I also set the initial memory to that size, dunno if it was important though, I also didn't test other settings)
I wonder why its only set to a gig? I mean its 2018, you prolly gonna have to search for boxes with only so little rams ...
