Remove an empty extra frame in unity animation

Hi @Zodiaq , I am fairly new to unity, have this issue also, not sure if it is causing or influencing my key current problem with this animation, can't keep state at end, and my rotation for my 2D character in animation works in the clip in editor, but doesn't happen in the game.

The extra frame seems to happen, yes, as soon as you drag sprite onto the clip, where it adds a redundant frame at the end. Or if I select sprite from within add Property in the animation clip, same problem.

Note if I remove the sprite from the final keyframe of the animation clip, this will stop the whole clip overrunning by 1 frame. So maybe this is what we're supposed to do? This is deliberate perhaps for some reason?

I'm beginner, so anyone who can advise why this is designed like this, thanks kindly! So it seems to be 'padding' any sprite property added to keyframe within clip by 1 frame extra, so if you are more than 1 frame from your final keyframe, it won't extend the clip. Does this mean we're not supposed to put any sprite property on final key frame?

Same problem here, what is happening Unity ? I'm using animations for a long time now and I never encountered this issue before. Recreating the animation doesn't fix the issue. Did anyone managed to fix this ? Unity 2018.3.8f1

Do you have a solution to this problem? Same happend to me!

Did you find any solution?
