All day today I’m having trouble when selecting objects options a random set of my selected objects change position or when I create a group my game crashes 3 out of 4 times anyone else having these problems?
I have had issues where ungrouping a set of objects has caused my game to crash, as well as Splinter Turrets randomly floating away. I’ve had the same problem you described first a few times before as well.
When I select multiple objects and press x they change orientation unless I group them, and if I group too many my game crashes 
this has been happening since hammer storm update.
