♦ Reproduction steps :
- Find a smol round crow foe. (Mafia for example cannot trigger the bug, crows are the only ones I tried who could.)
- Dive forward without hurting the crow.
- While prone, wait for the crow to hit you.

♦ Effects :
You will become unable to :
- Use the ice hat. (All other hats work fine)
- Dive forward. (Trying so will cause Hat Child to go prone without actually diving, as if you were standing still.)
The effects dissipates after jumping.

As benin as it may sound, I found out this bug while doing the "Mafia Jump" Death Wish; it was a complete run-killer there !
