Hah I work full time, usually 50 hours a week on average (I also have 2 other companies), luckily I am a Creative Technologist so it’s my job to tinker and know everything about different tech so this is actually what I do at work a lot of the time 
You have to just try and squeeze the things in where you can and take advantage of the learnings.
That mesh array is generated when it steps through all of my building blueprints. Another event steps through all of those blueprints and finds all the static meshes and add’s them into that array if they don’t already exist in there. If it does exist then I just flag what mesh it should be. I don’t actually really need that array there anyway I think I might have removed it now.
