As it says in the title, when a healthkit is taken over a level transition, it no longer heals the player when damaged, and acts as only a prop.
Steps to reproduce:
- Find a healthkit.
- Carry the kit to a level change.
- Get injured, step onto the kit.
- Don’t get healed.
Tested several times at multiple different levels. Haven’t had the opportunity to test if touching the kit to water restores its functionality (sounds weird I know, but works for a similar sort of bug in Garry’s Mod).
