i know the hotkey is shift + arrow keys but today it’s not working. i cant only move it back but not forward. it just creates a new action instead. (gyazo jumpscare)
This looks a lot like nodes are too packed together. Its common for OFS to drop nodes when you move them and they were within 1 frame of each other.
While i cant check the code, i suspect it tries to move the node, but detects the next one (which at that point isnt moved yet) being too close, so it drops it. And this can drop several nodes in 1 action.
Moving can then also align the first node with a frame, causing a later node to move even more than 1 frame, and then also get within that frame where its thrown away.
The other direction doesnt break here since the order of processing now first pulls them apart.
The worst part is, this even happens if you placed the nodes at the frame exactly (probably due to some floating point rounding).
My usual solution if such close nodes are required often is to change the fps (in my case i just recompile the video with double the fps). But this isnt very practical.
Yeah seems to be a fps issue. Try override the fps to a higher value, or try using cut + paste instead.
