I made a demo 'game' and the only thing that wasn't triggering rumble seemed to be Battle Trigger. In my actual game what aren't triggering are Battle Trigger and Deal Damage. I did not try transfer but wasn't planning on using that in my game. I am running standard Battle Processing with no plug-ins affecting Battles. I was using a simple shop plugin but wasn't satisfied with it anyway so I disabled the plugin and used default Store Processing and the Buy/Sell rumbles are working. So in the demo and my actual game Battle Trigger wasn't working and only in my game was Deal Damage not working.

I am not really sure what is going wrong for you. Could DM me on RM Web Forums or Discord with a game where the rumble is not working so I can download and take a look at it, as all of the auto rumbles work in my test project so it is hard for me to troubleshoot.
