Using the demo from Github, I decided to load a different TMX file. ( I just edited the level03 file to make it bigger) and now I get a:

it breaks at line 139 of TiledMapReader.cs

Any reason why it does this? I reloaded the original tmx files, and it does fine and the edited file builds ok in the pipeline tool…

It seems you have 2 identical keys in the same definition file. A copy/paste and you forgot to rename something to avoid this ? (Same problem as 2 root tags in XML)
