Viewport not showing changes in image sequenced textures

Hi there,

I am playing around with some 2D animation by way of having multiple planes with various image sequences on them that are subsequently controlled by key-framing offset values. This renders perfectly fine, as intended. However, when running the animation in viewport or when scrubbing, the textures do not display the correct image. Usually if I select one object, and scrub around it eventually corrects itself but the other textures don’t update.

I’ve tried switching between textured/material views, enabling auto-refresh in nodes, but I can’t seem to get this to display properly.

Anyone have any tips?
