[Bug] Fire time out of sync

[baron]

Summary: Fire burn longer than it should

Version: v0.346

Platform: OSX 10.11.5

Location: everywhere

Reproduction Rate: Everytime while sleeping or passing time. I am playing currently the nomad challenge and didn't check if it happens in the sandbox too. 

Description: Buildig a fire it says for example burn time 8h30 i rst for 8h look at the fire and it says remaining time for the fire 2h10 (not shure about the exact difference) went to sleep for 2h again, fire time remaining 40min. There is clearly something out of sync. I searched in the forum because I was shure that there would be another bug report but could only find an report for an much older alpha version. So I am sorry if I reported a bug that is already registered.
