After recent klwp update fade animations trigerred by globals don't execut correctly when global is "on" upon saving. When you set it off before saving it works ok. The problem is also with fade animations triggered by list global, it will only work for the item selected inside the editor.
Here is a simple preset with this issue.: https://www.dropbox.com/s/v35rgbl25gcxwvu/fadebug.klwp?dl=0
How to reproduce: load the preset, set global to on, hit save.
