• You can put portals inside portals
• you can glitch through blocks
• existing portals just move instead of despawning and spawning again

Oh this has to do with an update Immersive portals had that added animations when portal properties are changed. I'll remove this animation on my portals

Portals stay after you die, unable to reset them.

maybe make an extra issue for that idk

edit: the anims are fixed

fixed in newest release https://github.com/MeowMC/PortalGun/releases/tag/v3.0.2
