When a potion effect has a duration equal to or higher than 1639, its duration is displayed as "**:**", see also
This implies that the potion effect lasts forever, but this is not the case. However, because of
MC-44936 the client will not notice when the duration becomes lower than 1639.
Important: If this report is considered invalid, the field net.minecraft.potion.PotionEffect.isPotionDurationMax should be set to false by the method net.minecraft.potion.PotionEffect.deincrementDuration() if the value is below 1639.
- Use the following command
→ The duration is displayed as "**:**"
- Reopen the world
→ The actual duration is displayed and is decreasing
