@kennycason it’s only on master branch for now, you can use libgdx “1.9.11-SNAPSHOT” to have the fix.

To reproduce the issue you just need your game to load an animated map. Sorry I can’t post the source of my game. But you can check the source code of LibGDX, it’s doing an illegal type cast from AnimatedTiledMapTile to StaticTiledMapTile. It worked fine in 1.9.9 with the same map so it’s something that was introduced in 1.9.10.

BaseTmxMapLoader.java:656:
    staticTiles.add((StaticTiledMapTile)tileSet.getTile(firstgid + frameElement.getIntAttribute("tileid")));
