@GalacticGod There is an option for me to set the default animation in DragonBones itself, however I have found through my own play testing that it made no difference so I tend to forget about it.
If me forgetting this step is causing issues then I apologise. However I ask that you first confirm that it is a fault on my end. Update all the relevant plugins (yanfly's core,battle core, dragonbones, etc.) and turn off all others keeping only the bare minimum requirements; in case you have a plugin conflict as I have personally tested each and every one and they all worked, though I'll admit my maker is not fully up to date.
In addition try downloading my
WildBeast-DayMane to see if it makes any difference since I know I set the default animation for that one correctly. Because if this guy doesn't work either there is nothing I can do on my end.
