Animation sprites that are tiled with canvas walls are delayed by 1 frame everytime it is tiled.
For example here is a simple 1x6 sprite I made to test if this was an actual bug or I was just going insane.
As you can see, with each time it is tiled the frames for the animation are delayed by one, they should be all counting in sync.
Here’s the sprite I used to test.
I only realised this bug when a sprite drawn in aseprite animated seamlessly when tiled, but in TU it wasn’t.
