Hi! Normally we used to use “object pivot location” from source local → to → absolute world space. But for some reason that is currently broken and it needs to be switched to: Source(Instance & Particle Space) → Destination(Absolute World Space). I tried it in 5.1 with both the foliage painter & the procedural foliage volume and it is working as intended again 
( find the wind functions within the foliage shader’s and adjust)
