Hey, here is a rather obscure but easy to duplicate bug I've stumbled across. Probably easy to fix. It occurs in the Enemy Editor's enemy selection list.
In the above image, you'll see that the Leever's sprite is displayed correctly in the upper right. Everything is fine if you click on an enemy name or scroll to it with the arrow keys or PgUp/PgDn.
However, look what happens when I press a letter key (in this case, V):
It scrolls to the first enemy that starts with "V," but the enemy sprite preview does not update. A Leever still shows in the upper-right rather than a Vire. Yes, I have tried this with several different enemies to make sure it is a bug.
That's all for this one. I have a different bug I will post later, but that one will require an example QST file for good measure.
