WSOD when removing item from cart in combination with currency resolver module.

Describe your bug or feature request.

Whenever I remove an item (the only item) that's in the cart using remove button, I am receiving a WSOD.
This happens only if I switch the currency mid way using currency resolver block (more details below).
Here's the error:

The website encountered an unexpected error. Please try again later.

If a bug, provide steps to reproduce it from a clean install.

Commerce Core 2.25
Commerce Currency Resolver 1.60
(I have internal page cache disabled, if that matters, I had to disable it to make currency resolver work for anonymous users).
The currency resolver is set to work on Cookie (currency block selector).

I am also using a promotion that's giving 10USD off for every purchase above 50USD, not sure if that's relevant.

I am testing an item, 1000EUR worth \( ^_^ )/

1. Adding it to the cart using a user (regardless if it's just authenticated user or superadmin). (NOTE: if I remove the item at this point, it works fine).

I have a Currency Resolver block at the bottom, in the footer area. The item is displayed in EUR.

2. I click on the currency resolver and change from EUR to USD (if I go the other way it's same result).
3. Ok, now I want to remove the item, after the currency change.
4. WSOD (the one included above).

NOTE:
The WSOD happens only whenever I click on the remove button. BUT, if instead of Just put 0 instead of 1 in the items number. That clears the cart without any error.

So yeah, big think.
Hope you guys can figure this one out. For now I will try to make a button myself that would change number of items to 0 as a workaround.

UPDATE:
Did some more testing.
Just to add here.

The error does not happen if I change the currency prior to actually adding the item to the cart. It happens only if I change currency with the item already in the cart.

Also, promotion does not affect this. I have tested without the discount and the same error shows up.
