Don't worry, we know it's a nightmare. :b
I have a hard question, and i don't know if you can answer this if you have a bit of time of course...
If trying to fix Rengar's code it's more like a spaguetti, how much time you guys (various rioters, not only you bcs it's a lot of work and time) can work to do a "new Rengar code" deleting the current one?
I'm not a code/vfx/sfx/animator designer, and for me it's easy to say this question, but for you and other persons knows it's another thing.
Hope in a future, his code can be totally fixed.
This is the kind of thing that's possible for projects like this actually, decent chance we do this
