When recording an action with blockbuster and then replaying that action using the command "/action play ", the command is not executed and an error is thrown:

Removing Astral Sorcery fixes the issue.
I'm using AS 1.10.11 and Forge 14.23.5.2811

Already fixed in-dev by forcibly nulling out the wrong player class call in other mods when it comes up, wait for 1.10.12.

The issue is that blockbuster is calling the improper player class, by the forge documentation.
