About this project
What does Bugrock add?
Bugrock
A mod/datapack that recreates common bugs inherent to the Bedrock edition of the game.
Bugs
I've added the most common bugs I can recall:
Regular freezing. When a lot of monsters are near the player, the game freezes, and after a few seconds, the mobs stop lagging and move faster than before.

Disappearing blocks. When a player crouch-walks and builds blocks, they notice after a while that they're starting to disappear. This happens right before the player's eyes, and the key is to not be over a chasm.

Chunk loading error. When a player flies on elytras, chunks often don't have time to load, so the player doesn't see them loading. But sometimes the game simply ignores chunk loading and returns an error. At least the damage doesn't go away.

Rollback The first useful bug is when the game forgets the player's last actions and returns them to their previous position.

Lightning (bonus). Who hasn't experienced all their belongings falling out of their pockets after death, only to have them immediately burned by lightning? Every time. Enabled/disabled with the command
/trigger bizcub.bugrock.lightning.trigger.
