Mod Version: HardcoreRevival_1.15.2-4.0.1.jar
Forge Version: 31.1.41

Expected behavior:
Revive after clicking "Accept your Fate" button.

What Happened:
Testing my custom mod-pack on my 1.15.2 server and loved the idea of this mod. For testing, I flew up into the sky in creative mode, then /gamemode survival and fell to my death. After clicking "Accept your Fate" button, nothing happened. I pressed it a few more times and took a screen shot to show. The only way around it was to then press the "Escape" key which removed the "Accept your Fate" button and replaced it with the traditional "Respawn" one.

Update, this seems to be fixed in the latest forge.
