Title. I have absolutely no idea why this mod would cause this problem, but I removed it and the issue resolved. Now the problem is that I can't spawn in the dimension I want, and all of the other mods suck because it's a cave style dimension I want to spawn in. My best guess is that the spawn invulnerability is just broken sometimes, and not disabling itself, maybe?

Same issue on single player and on a server.

steps to reporoduce:
Create a new world
Kill yourself
Respawn
Kill yourself again within about a minute
Expected behavior: you die
Actual behavior: you don't die (about 60% of the time??)
Can't even use /kill (Chat logs that the player was killed, but I am not dead. I have tried this multiple times)

I tested this on both singleplayer and a dedicated server. I have absolutely no idea why this is happening. This mod shouldn't have anything to do with being unable to take damage (that I know of). I'll provide more info if needed.

I haven't tested this with the mod on its own independent of other mods, so maybe there's a conflict, but in any case, here is my mods list:
