I wasted 1 day on fixing a bug, only to find out that there's a simple solution to it!

This is called "learning" - good job.

I've done that. It is not fun when that happens.

Lol same thing happened to me. It took me 3 hours to realise I hadn't checked a box in the blueprint. 

bro same here , every time i fix a bug another bugs apears from nowhere

The struggle is real :(
