Invalid Payload makes attack buttons grayed out

[mcgyver5]

Burp Version: Professional 2.0.11beta Java Deserialization Scanner v0.5 ysoserial-0.0.6-SNAPSHOT-all.jar compiled (on Windows) as follows: mvn clean package -DskipTests -Dhibernate5

Noticed a problem where due to a typo, the extension gets into a state where the buttons are grayed out and there is no apparent way to bring them back

To Reproduce: in "Exploiting" tab, type invalid payload name (like Hibernaee1) and click exploit. Buttons become gray as if it is working but they never come back until I restart Burp or uninstall the extension and re-install it.

Any update on this? This still seems to be an issue
