Hey man,
Thanks for all the extra input 
Will give it some thought/try moving things around a bit, but yea, currently its finally workin after about 1,5 week of trying, so not too eager to break it again 
I did try this a bit already, and it appears that im sorta stuck with the current order of calling the different functions, if i move stuff around i either stop getting the overlap events, or crash the engine.
One thing to note, is that the code u shared was for 4.12, and im on 4.14, some of the syntax/arguments changed and some functions appear to be redundant now, like if i comment out the RerunConstructionScripts bit i actually still see the component show up in the editor at runtime, and can be edited as i see fit (wich helped in testing) so something changed there between .12 and .14, or how my NewObject has different arguments then yours, both of those are due to different engine versions.
Either way, yea, thanks a million man, ill play around a bit with putting the RerunConstructionScripts back in, but if that doesnt fly (read; crashes the engine or stops overlap events) ill just omit it and accept that what i have now is the way to go.
Next i will probably turn it into a function like you did so its easier to re-use 
Thanks again, much love <3 :o
