Note this is for v14 only:

1. When using the Rotate Area behavior a tile gets rotated wrongly because the x and y of a TileDocument is the center of the tile. Some math in the behavior is therefore no longer needed for Tiles.
2. Currently for "updating" the placeable doc inside static #animateFrame it uses Object.assign(doc, updates);. This appears to be not accepted by v14 and requires it to be doc.updateSource(updates); then the animation happens smoothly again for all placeables.
3. Apparently not necessary but maybe advisable but in the same static #animateFrame, is to also change the wall's assignment of c instead of doing doc.c = [array] also doing doc.updateSource({c: [array]}); for consistency only.

EDIT: updateSource is not the solution it locks the Token document in place afterwards... investigating further
