The backgrounds work fine in Playtesting mode, but once the game is deployed they disappear (Like, if the plugin was not there, but it is) . Also, tried using other project and the result was the same.

I am not encrypting or excluding any file. 

Thx in advance. 

Also, you should be able to freely encrypt the files, but since I don't know how to control RMMV's exclude mechanism, you might wanna avoid it...
