I had a main cell that (I think) was able to digest all types, but I engulfed some prey using a different cell. This cell couldn’t digest the prey and got rid of it. Should the notice show up for this anyway, even though the main cell type is able to digest it? It doesn’t seem to right now.
I knew about this limitation when I wrote the HUD notice message system. This is the issue about other colony members forwarding their notice messages to the player (which would then show them like normal, if I read your post right this is the thing you noticed):
