I’m using the Github version of 4.14.3 and have noticed something odd with the blendspaces. I will describe it while showing the steps necessary to reproduce this in a fresh 3rd person project (any project with animations should do though):
When making a new blendspace, the default divisions are 4x4. When dragging an animation to the top row middle column a dot representing that anim shows up where expected. But when moving the mouse it behaves as if the anim was placed in the bottom row middle column instead. When placing an animation there, a dot shows up, again as expected, but the actual animation seems to be at the top of that column.
I asked a friend to reproduce this, he was not able to do so, but even redownloading the engine has not fixed it for me.
