I'm just taking a look at this now. The reality is that 4e is very low priority for fixes because I dont own any of the content, due to how its licence data was provided. So for me to test this sort of thing I actually have to 'build' npcs and powers from scratch as data... so as you can imagine it takes some time to setup and test and replicate.
I'm away at the moment, hence the delay. Once I know the issue and can replicate it, I'll try and sort a fix. I'm not sure I have everything on my laptop to be a make an update/upload. So even the fix will have to wait until I get back to my development machine and source control etc..
