Hello, I have a bug regarding sound in automization.

This "sound" occurs only when I am near working 90 degree inserter only, all other parts don`t have this problem.


Here is log:
0.000 2015-08-07 22:16:18; Factorio 0.12.3 (Build 16287, win64)
0.000 ...

Any progress? Having this forum on tapatalk will be cool
