As you may be aware, we're currently experiencing service disruption across both game and web services, this is affecting both RuneScape and Old School RuneScape.
We are aware that RuneScape (as well as other games) are being targeted by attacks which are causing connectivity issues for our players.
We are doing everything we can to mitigate any impact on your gameplay experience - our Systems Team are currently working to improve stability across our core hosting platform to improve the situation.
Whilst this is ongoing, we would strongly suggest that you do not partake in dangerous/high-risk content such as PvP or high level PvM and as always, don't risk anything you're not prepared to lose.
Unfortunately, Old School RuneScape does not have the tool required to roll back or to confirm what items were lost by players and it will not be possible to refund any lost items.
Should you need to get in touch with Customer Support, please use the Support Centre on the RuneScape website.
