Reference to self doesn't work for function anymore

Don’t worry about it. Since my update to 4.15 the error dissapeared magically.
My programmer is going to rework the whole thing(I’m bad with this) anyway so it doesn’t matter anymore as well.
But thanks for digging into it again, really appreciating your support.
