Placing a Mob Spawner in world results in a server crash due to a Null Pointer Exception when the server attempts to invoke the Mob Spawner Entry class _1952.method_38093. This results in a block entity ticking error. Removing the mod resolves this issue and removing the offending spawner then re-installing the mod works as well.

Should be fixed by 2.0.2
