Simulation and AntiKB falses when hitting/trading hits in non stationary water

[c0dingnoobi]

Describe the false positive and how to replicate it

This behaviour is only reproduceable on non stationary water. Video: https://youtu.be/jrsPidaUYEU?t=19

1. Load GrimAC using default config
2. Place a bukket of water on flat area.
3. Hit Player while walking towards water stream --> falses Simulation
4. Make both players hit each other --> falses AntiKB
