dragonmaster95. I remember that I did not used capital letters, because I know You can't use them since 1.13, so, I Will send a video showing the bug for Michael Wobst later.
It is the same cause that do that if you summon a ender dragon it just fly in circles?
I can confirm it
Other part of the bug is that, if you summon another entity Where the invisible was, the new entity Will be invisible When you go far and return
Ok, so, I tested without capital letters, and I did another test with slashes. So, I appears that It fixed, since a I reported this in 1.14.3 pre-release 1. Thanks for your time and your comments 🙂
