Sweet Berry Bush deals damage twice when walking through in 1.12.2.

[DesolateIntention]

Description:

When a player walks through a sweet berry bush in 1.12.2, they take damage as expected, but then take damage again approximately one second later without any further movement or interaction. This appears to be a double-damage bug.

Steps to Reproduce:

1. Place a sweet berry bush.
2. Allow the sweet berry bush to grow to the stage where it deals damage when touched.
3. Walk through the sweet berry bush, ensuring you only press the forward key (W) once and release it immediately upon entering the bush.

Expected Behavior:

The player should take damage only once upon entering the sweet berry bush's hitbox and making contact with the bush.

Actual Behavior:

The player takes damage once upon entering the bush, and then takes damage again approximately one second later, even if they have not moved since the initial contact.

Version:

• Minecraft: 1.12.2
• Forge: 14.23.5.2860
• Future MC: Future-MC-0.2.20

Notes

The bug can be triggered by any movement, not just forward movement (W key).
