Teleporting animation

[DyCh]

So, I made a animation of a stick figure climbing a ladder. And I converted it to a symbol so I didn't have to remake the frames each time. I had the symbol go a total of 5 times, it only messed up on the last 3 symbols, I DID classic tween the last 2 symbols but I don't understand why the first symbol would be impacted. Is there a way to fix this?

Also please ignore the people in the back, even though I'm in class my teacher is just not helping me so I'm asking here.

most likely there are keyframe problems where you see the unexpected movement.

The thing is I'm using the same symbol multiple times but it only has those jumps 3 times on 3 of the different symbols at (I think) different times on those symbols

[DyCh]

Also while checking/previewing the symbol alone no errors happen

if the jumps are at different times, then there's a performance problem.

So is there nothing I can do about it?

test it on a better spec'd computer.
