Trader Buy Fails

Category: Code

Reproduction: more than 75% of the time

Online: Occurs online, haven’t tried offline as don’t play that mode
Most servers I play on have a ping time between 40 - 100ms. This MAY be a factor.

Maps: All

Specific Trader? No, occurs at all

Summary:
Round ends and Trader path loads.
Run to trader, time remaining can be any amount, occurs at any point during purchases.

Symptom:
Enter trader menu, click “Auto fill”, money debits from Trader menu balance
press “Esc” to exit the Trader, money is still as it was before entering the Trader, purchases have not occurred.
This usually occurs 75% of the time.

Enter trader menu, click each item, press ESC after each purchase to exit Trader.
With about a 50% occurrence rate, you either “purchase” the item, or once you leave, haven’t. Re-enter and again, try your luck.

Enter Trader menu, do a complicated transaction, sell an item, buy an item, fill a couple of items, transactions appear to have worked.
Wait a moment, Exit Trader, transactions have not occurred.

Finally, I noticed the transaction “rollback” in the Trader menu last night.
Did a simple sell an item, manual fill some items, Trader menu cash went down, then about 2s later, went back up… items were all screwy.

OS: Windows 8.1

Install: multiple attempts to Steam Restore and even a fresh OS reinstall lately.
