[.32][Graphics] Missing pictures of Ebbenwolf after load

I've had missing pictures of pioneers and a custom infantry unit after loads.

The Ebenwolf pictures of my rescued pubs disappeared after a while too.

I also noted that Ebenwolf pups simply disappeared from a Town, that was never attacked, without explanation.

Carried on, as the game was early on. Will make a save next time, if it happens again. 

Same for me.  Before load they were fine, after load the pictures were gone.
