First time logging on after the new update and when I opened the store I have -135 shillings. Definitely had more than that before updating.
Hi @WindblownRebel,
It’s likely due to a backend hiccup - this kind of issue tends to resolve after restarting the Steam client (possibly a few times).
This happens to me a lot IRL when wife goes shopping.
Is it the same for Xbox users?
I’m sorry your wife doesn’t use her own account, I leave my husband’s alone just fine. 
It should resolve in the same way for Xbox!
