Currently tar lamps, that are placed on the ground and turned off when you save and quit, will be turned on again when the player relogs. This makes it impossible to store tar lamps on the ground, because as soon as one relogs all tar lamps will turn on again and soon turn into ash.
The lamps shouldnt burn on their own again when a player relogs.
Steps to Reproduce
1. Put Tar lamp on the ground 2. Right mouse click tar lamp to turn it off 3. Save and quit 4. Relog 5. The tar lamp is burning again and will soon turn into ash without being turned on.
This issue has not been confirmed by a developer yet.
