Order Status Update Error - Random stuff going on

Hello,

I am using OpenCart 2.0.1.1

The status of the order will not update on some orders (the ones from this month)
When the following error was detected there were no recent changes made to the code of the site, no modules were modified / added.

Old orders will update.
New orders lack will not work completely.

So if I want to update the status from "Processing"(default) to "Complete" : I choose the new status and edit my message and click "Add History"
=> emails get sent, an extra history entry gets created, a success message is displayed, BUT the status remains "Processing"(default).
This only happens to new orders (Received this month).

No errors are displayed in the Error Log or elsewhere.
Old orders can be updated and work.

The random factor is that I managed to successfully chance an order status of a new order once, but could not do it the next 10 times.

I have no idea where to start
What are your suggestions ?

Do the orders in question have a coupon or reward points?

I have noticed a similar issue with v 2.2. I'll select order history "Shipped" but when I save, it saves as "pending". I have to go into the database to change the status manually.

Btw. one just did it to me again and this one did have a coupon used on it. Cannot say about the others for sure, but it is possible. I do not use reward points though.

Edit: Q I think you hit it on the head. A second order is doing the same thing and it uses a coupon! Is there a fix for it?

No they do not have coupon or reward points.

Anyone ever figure this out? I'm still having this issue for orders that have coupons used on them.

Figured I'd bump this one more time since I cannot figure out how to get order status to update correctly if a coupon is used on the order. I have to go into the db to set it. Would sure love to be able to fix it.
