Game is stealing resources during building upgrades

I noticed this happens when the required resources (for an upgrade) are very close to the displayed available resources. The bug is very likely caused by a discrepancy between the displayed amounts and the real resource amounts on the server. It looks to me that upgrades happen like this:

1. If the displayed amounts are enough for the upgrade, allow the upgrade;

2. When the player pushes the upgrade button, the client (in-browser-game) checks if the amount of resources are available and if they are, it sends the server two commands:

2.1 Deduct resources Y and Z from the player's account;

2.2 Upgrade building X; 

3.1 The server executes 2.1 and deducts the resources from the account

3.2 The server checks for the actual resources (on-server) and if they exist it will upgrade, and if not... no upgrade.

Assuming I'm right, there are two sides of this bug:

1. The server should check for resources before anything, and only initiate an upgrade if the resources are available, deducting the resources only if the upgrade succeeded.

2. The server should reject upgrades if there are not enough resources and forbid the client to deduct the resources from the displayed values.

I might be wrong about these details, but I don't remember seeing the issue when I had an excess of resources when I upgraded something. So in conclusion, the safest way to prevent this bug from showing up is to be patient to gather resources well over the displayed amount, just so you don't get hit by the discrepancy bug (weird conditions in the code).

I have the same problem, this has ruined the game for me . 

same problem here, deducted tiberium and power for the last 2 of my buildings upgrades (Command Center and Defense Facility from level 41 to 42) but buildings are still on level 41... it's a lot of resources...

it happens all the time, even if you have 20 times necessary to optimize resources.
you don't notice it if you optimize rapidly, that's the scam

I talked about this problem with a dozen players who also have this problem but had never noticed before

same thing for me is now happening on wrath4.   

totally unacceptable for a game thats been running this long now.

This needs to be addressed immediately.

the same problem on wrath 4. not once, many time... it is happening from the begining, many players reported that issue but nothing had been donne yet. 

Hi to All!
I am writing this message to report exactly the same problems like resources disappearing when I transfer them to one base from another or, just by upgrading buildings or units.
This time I was, on Wrath 5 server, ready to transfer 2,5M Tiberium from base 1 to base 3, and clicked the transfer button, then it pop up a message saying something like this "this base is not able to receive resources" and the 2,5M Tiberium are gone.
I refreshed the browser tab game, and nothing happened, and now the 2,5M Tiberium (so much needed for me), are now totally gone, simply disappeared. Yes, it happened, and the problem is that it's not the first time that this situation happens. It's sad, very sad to see it happening. Please I want my resources back so fast as possible. EA, do what you have to do, but I want them back.
And worse, one other bug that keeps happening to me, why is that when I click to upgrade buildings or units( and I make sure I have the needed resources on the limit, to that upgrade), I click upgrade, then the building/army stays with the same level as it was, but a part of those needed resources for that upgrade, is gone making it impossible to upgrade the building/unit again? Why is this happening all the time??? I want EA to solve these bugs, or whatever they are.
It's unacceptable that these situations continue to happen over and over again.

I want EA to hand me back the stolen resources, for yesterday, as these type of situations happen very often to be called bugs, it's like something programmed to happen once in a while, which is very unacceptable from Electronic Arts. So, with this said, I want to watch this real problem solved.

Thank you.

Best regards.

I am experiencing this in World 33.....A LOT!

I just sold a barracks(lvl 60) and upgraded two other buildings to lvl 61...all good.

Then I took one to lvl 62....all good

Then the other, despite having more than twice the required funds, when trying to take that to lvl 62 the funds vanished but the upgrade didnt happen!

EA this was 153Gig of Tiberium! and the third time it's happened this week!

I am too MAD to calculate how much that would have cost to buy with cash! it represents hundreds of hours playing over the last three years though and it stinks!

Same issue on Wrath 5. This has happened several times across tiberium, crystals, and power. Just did an upgrade of a wall from 16-17 that was supposed to cost 76K tiberium. It took over 700K when I clicked upgrade!!! Same thing with power. It was supposed to cost about 19K, but it took around 200K. Please help resolve this...
