You're not crazy the same thing happened to me!
When I signed on this morning I had 1633 coupons and 200 ingots

After signing in I did a daily check-in, upgraded my charms for the rebate, did group wheel and then ran some convoy. In the middle of a convoy I got kicked offline. When I refreshed it gave me a white screen so I close the mini-client completely and restarted. When I restarted and finished my convoy, I realized all of my coupons were gone and I only had 88 ingots left. I KNOW I had the coupons when I logged in this morning because I was checking lucky board planning to use them later. I did not spend anything anywhere. I've never spent any of my 200 ingots since getting them nearly a year ago now.

I cleared my cache, restarted the client about four times and tried browser version and no luck. It's all just gone.

I have no screenshot from earlier today when I had them because why would I screenshot myself first thing in the morning when nothing is wrong? I DO have one from last night though from right before I signed off for bed that shows how much I SHOULD have. The only thing that has changed is some coins and my power from the new myoboku thing and upgrading charms today.

I'm super stressed, I've been saving them for the past month for lucky board and now I've got nothing

I sent in a bug report through the client support, but I'm glad there are other people with this issue, it's not just me.

I did upgrade my charms! I had around 600 total but since I only needed 500 for the rebate I didn't use them all. I only upgraded my charms from levels 3 to 4 or 4 to 5 which are pretty low cost anyway so I could guarantee not going too far over the 500 I needed to use so I could save the remaining for the next rebate.
In the charm rebate I used 528 total

and looking at what I have left over I DO have more than 200 remaining, even though I only had about 620-ish when I started. This is far more than I should have left.

The fact the auto-upgrade took from our coupons and ingots instead of using the charms we already had in our inventory to begin with is ridiculous D:<

I also have never checked that box,

but I remember there was a bug with the thread in battle armor when 3.0 first came out that using the auto-upgrade, even without the box checked, it would give you a popup asking if you're sure you want to purchase thread. Could this be a similar issue? Still doesn't explain the load of extra material in our inventories though. And even if the box was checked, it should have given a warning/confirmation that you were about to spend coupons.

I got a reply to my report three days ago saying "The situation is under investigation. We apologize for the inconvenience. Thank you for your patience and understanding!"
Today I checked back to see if there had been any updates and about a half hour ago my report form has now been closed as "Resolved"
....But it hasn't been resolved. I've gotten no updates regarding what the problem was, what happened, nothing. Why is it 'resolved'???

Thank you Daiske

I'm also 100% positive I did not check that box. I'm very aware that box is there and always make sure it isn't just in case because I'm paranoid of accidentally spending coupons I don't want to.

As I've mentioned before, when 3.0 was implemented a similar bug happened with thread in battle armor. When you went to use the auto-upgrade tool even if you didn't have the box checked you would get a pop-up confirming you want to purchase X number of threads and would not allow you to upgrade at all unless you did. This problem was fixed fairly quickly after bringing it up and no one has had an issue with threads since. With charms though, there was no pop-up. Even without the box checked it just took all of our coupons without any sort of confirmation, without us even realizing.

Even if coupons/ingots do count as material, if I have 100+ charms in my inventory and an upgrade requires only 40, it should not take from my coupons before using the material I already own. That just doesn't make sense.

I'm sure you can understand after a week of a vague "we're looking into it" message followed by saying it's resolved, forcing us to re-open to get any sort of progress report and one that reads as "this is your fault not ours" like nothing we've said has actually been taken into account; it's incredibly frustrating. Especially when multiple players who have been here for quite a long time with no issues all report the same problem on the same day right after a major update individually.

As upsetting as it is, I'm not too concerned about my own situation specifically at this point. I'm not a big spender nor do I keep close track of every move I make in the game as Kira does. However it's very unfair to players who have spent a lot of both time and money, and to future players who may run into this same problem, if this isn't investigated thoroughly and fixed so it can't happen again. So please forgive my impatience.
