Guild Wars 2

I posted this in another thread but their loss was due to the server rollback from the other day and I decided I might be better making a new thread since this only just happened last night

I tend to ramble so Im keeping this as factual as possible
Leveling weaponsmithing 196 I want 200 before I sleep so I can craft new weapons next day
Go afk to get drink and snack and I come back game is threatening to kick me for inactivity
I move my character and head to the trading post to buy materials for inscriptions
I craft myself to 200 hang around a bit while I check hero menu and mentally add up what materials I need to craft my new weapons
I exit to desktop
This morning the weapons are still in my inventory and my amount of money is the same but my skill level is back to 196 and I still have the discoverys for the weapons I crafted
Granted not a huge loss but a very frustrating set back and it worries me if this sort of thing could happen again only the result would be worse?
