Eerie Mojang Office Party subject to random crashes when performing actions

Random actions in the Eerie Mojang Office Party cause the app to completely crash, destroying all progress. Examples include killing mobs in minigames or clicking on menu boards, and their randomness means it makes for an extremely frustrating playthrough.

To replicate:
1. Open the event on your iPhone
2. Try playing through anything. DON'T click on any menu boards since another bug means it is impossible to close them.
3. Eventually, the entire app will crash randomly.
