Fill Her Up 2.11 Beta Expel Cum Problems

[tobeto]

When pressing the hotkey, my character will play an animation but it stuck there, nothing expel out. Pressing the esc key stop it, then it equip and unequip the Inflater LeakV item. The "Deflate Fail Chance" animation works but not the animation when you successfully expel it. It just stuck midway, the stamina bar just reduced to half then go back up instead of being consume.

I used FHU in the past, the older version works fine for me. 
Does anyone know any fix for 2.11? Or can you send me the older version please. Thanks
