The proper adjustments had been made but then you made a 1 ref donations before the previous donation was completed. Steam must have been slow in confirming the trade and at that exact moment your single ref was confirmed overwriting the previous payout.
You currently have 30266 credits and I have manually added an adjustment for 40320. On your next login you should have a balance of 70586.
If the bot doesn't instantly give you credits, you can always try and rejoin the server to see if the bots will update your credits as they do a check every time you join one of our servers.
