Yes, but it also overwrites the tempo node I set before.
I changed the tempo from bar 1 to bar 15,
if I set a new "beat at now" at bar 18, it starts recreating the tempo from bar 1 to bar 18. And before it used to change only the tempo between bar 15 and 18.
I think this happens because the created tempo before and after beat 15 is the same after setting "Beat at now".
Because when I change the tempo in the tempo view BEHIND beat 15, then I can set beat at now anywhere behind and THEN it creates a new node without overwriting the excisting node.
<edit 2> It happens randomly, I just tried it on another track and from 18 new nodes, it created 16 new nodes and 2 overwrites.</edit2>
