If an existing Painting entity is removed, and it is created again using the same Entity ID, it causes a client crash. This behavior is not shown on other entities, where they are created correctly.
This was discovered during world teleporting between different worlds in PocketMine-MP. After reproducing the problem, I discovered that it was caused by the client.
The steps to reproduce it (for developers) are:
- Create a new painting entity using AddPaintingPacket (0x99)
99000000020000007e0000004400000081000000010003536561 Entity ID: 2 Spawn X: 126 Spawn Y: 68 Spawn Z: 129 Direction: 1 Title: Sea
- Remove the entity using RemoveEntityPacket (0x8d)
8d00000002 Entity ID: 2
- Add the painting again using the same packet as the first step (time doesn't matters)
- Instant crash
Packet values are an example
This could affect MCPE 0.9.0 and infinite worlds, because if an entity is removed from memory, and you return to that area, a crash will happen.
Android devices, and Creative mode is also affected.
