If I pay for a Patreon subscription to have webm backgrounds and the program no longer loads them, I think it is a problem...

Im seeing the same issue, never had this problem before the update.

DDE reached out to me and I got the answer. Here it is.

"Click Open Library, find the fifth category called webm and animated props and open from there."

So yea, load your webm in, hold alt and drag it over to the main section as a background and voila!

This is a workaround not a solution. The background is treated as a prop. I have to load a dark backgroun because otherwise the fog of war doesn't work, the grid comports differently. I mean, wasn't it simpler that wbem could be loaded directly as background?

I just load it in paint and re save as a jpeg. It will load after doing that.

Thank you for the obvious. You obviously don't need aninate maps. But there are people who pay every month for the subscription on Patreon of these gentlemen to have new animated maps in wbem format which is lighter (which by the way they continue to create) but to be uploaded you have to use workarounds and they don't have the functionality as before, and in all there is not even an administrator to give you feedback
