Thank you!
As for your request, that seems to be a projectile system request.
There is an updated queued for the plugin but after Master Editor is complete
Hey there, I am open to upgrading the plugin. My focus is to get https://synrec.dev up first however
Hello, thanks for bringing this to my attention. I have uploaded a patch, please let me know if you have any further issues.
v1.1 - Minor calculation bug fix - RPG Maker MZ: Gauge Game Creator by Synrec

It's a bit strange you are having so much problems downloading it.
I have confirmed an issue with map motions and a patch for it is complete. Knockback, facing attack and Multi-tile battlers work as intended from testing.
It will be uploaded with better explanation of the newer parameters implemented over the plugin updates since then. I apologize for the inconvenience(s).
