Today 40min after my first dive I went into the simulator to show the underwater screen of the computer to a friend. (He has a predator and I was proudly comparing my new toy to his big brick

After showing him the screen I exited the simulator and noticed that my surface interval was back to zero. Don't know if it affected my tissue loading or not but I think its worth reporting.
The other thing that I found is that I was able to generate a desat loading after a dive simulation, This is what I did:
I was fully desat at the time
OSTC ON and connected to PC
JDiveLog 2.14
On JDiveLog > Dive computer > OSTC Dive Simulation > Replay existing profile > Selected my latest dive (dive started to replay)
Got bored and pressed "stop"
OSTC stopped the simulation and showed desat time on it and the surface interval started counting.
I simply made a reset of the deco obligation as I knew it had been 4 days since my last dive but it would have been a bugger today where I do have tissue loading and I'm diving tomorrow morning.
Thanks.
