On 1050x850 resolution the requisition tree has a text bug. The white text detailing the a special effect will be incomplete instead of on a new line when it is too long to be displayed on one line, such as in "Leader's Resupply" in the image displayed below, or any other requisition item with long white text.
A more minor issue is that tooltips can sometimes be partially hidden in the level up section by displaying under the other customization tabs, depending on where the cursor is.
Another minor issue, tooltips can sometimes be cut-off by the edge of the window depending on where the cursor was.
Steam, Win10, current version. I have not tested these on other resolutions.
May your death be remembered by all... and stop confusing me with Zer0winds!
