What gameplay feature is this bug affecting?
shift+click selection when making a transfer or trade

What's the issue? Please include any error messages you receive and as much detail as possible.
using shift+click to select and then deselect items when making a transfer causes the selection of items to become inaccurate.

using the steps shown below results in me seemingly having 1 abandoned nest selected, but the "x out of 200 items selected" counter shows that I have 0 items selected:


I initially thought that the counter was incorrect, and I actually still had the nest selected.

however, when I attempt to complete this transfer and send over the nest, I get the error that I haven't selected anything to transfer! so I actually do have 0 items selected.

to me this suggests that the top right counter is actually correct, and it is the rest of the selection area that is displaying incorrectly. (although that's just my guess, and I'm no coder, just someone who likes to make educated guesses.)

this can happen in trades as well, and with lions.

Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
made a gif for easier showing:


in the gif, I:
1. click the first abandoned nest to select it
2. while holding down the shift key, click the fourth abandoned nest to select it and the second+third nests
3. click the fourth abandoned nest to deselect it
4. while holding down the shift key, click the second abandoned nest to deselect it and the third nest.
