Thanks a ton!
Easily solved the first problem, for the third one: I already had a player controller with show mouse cursor enabled. I just forgot to enable mouse over events XD
The problem with the edge costs might take some time since I’m relatively new to UE4 but I think I get what you mean 
Edit: Unfortunately no more time today… Still trying to change the edge cost but that’ll have to wait 'til tomorrow
This looked most promising thus far but something still doesn’t work how I think it would…
