Just did a bunch of testing, it seem the Events and Movement Core by VisuStella
(http://www.yanfly.moe/wiki/Events_and_Movement_Core_VisuStella_MZ)
completely renders the copied events non-functional.
T-T

unfortunately not yet, it's a little rough trying to get two spawners to work together especially with obfuscation involved. I'm trying another approach now that you've reminded me about this issue which leans into the spawner that's inside of the eventsmovecore plugin. It's more of a workaround so here's hoping I succeed on this fresh attempt.
It's really a shame that Visustella decided to group their spawner inside of the eventsmovecore plugin which has so many other helpful features. So far I'm seeing some promising signs in my testing but transforming is an issue that I'm trying to resolve.
