Oh lovely, the forums decided to load for once. That's a fun change.
The Improvement system doesn't really play nice when adding multiple powers with the same name, currently it adds the first power, detects that you have that power, and tries to make it free again. The freezing you experienced is linked to that, in that there's technically a forced value but it's not coded to expect it, so there's technically another dialog window behind the Chummer window. If you pressed Enter it would've closed the window and restored normal behaviour. Unfortunately nothing much that can be done about it until I implement the powers rebuild, but that's run into some technical issues related to qi foci.
Anyway, Chummer 5.192 is now available. Big things are in the works, but the major notes for this version are that all of the relevant errata from Run Faster has been included, Book of the Lost's (admittedly minimal) content has been added with the exception of the alternate Raven mentor spirit, and a bunch of weird bugs have been fixed.
The one major important change you'll need to take note of is that by default, Chummer now does not show items over your maximum availability limit unless you have the Restricted Gear quality. If you can't find cyberware that's normally above the limit but reduced by Grade, you may need to reselect the category or use the Search textbox, due to the way the filtering works. You can disable this behaviour by disabling the relevant option in the Character and Printing tab of the Options window.
